How do I get the first row of a repeater, and get a sub_field from it?

  I read the documentation but it doesn’t work.

  I searched in other threads, and what I found doesn’t work. I have this massive piece of code:

  <?php
      $current_category = get_queried_object_id();
      $taxonomy = 'brands';
  
      // Get all products from this category
      $tax_query = array(
          array(
              'taxonomy' => 'brands',
              'field'    => 'term_id',
              'terms'    => $current_category,
              'operator' => 'IN',
          )
      );
      $args = array( 
          'post_type'   =>  'products',
          'post_status' => 'publish',
          'posts_per_page' => -1,
          'orderby' => 'title',
          'order' => 'asc',
          'tax_query'   => $tax_query
      );
      $products = get_posts( $args );
  
      // Create your new array to store your products in, organized by brand
      $products_sorted = [];
  
      if ($products):
  
          // Loop through all products belonging to this category
          foreach($products as $product):
          
              $product_id = $product->ID;
              $product_brands = get_the_terms($product_id, $taxonomy); // Return an array.
              
              // For each returned brand (cause it's an array), add the product to the final sorted array.
              // We're going to only add the product ID for simplicity, all other product values can be grabbed from the ID later
              foreach ($product_brands as $brand):
  
                  $products_sorted[$brand->term_id][] = $product_id;
              
              endforeach; // $product_brands loop
          
          endforeach; // $products loop
          
          // Now that all our products are in an array organized by brand, let's sort the brands by alphabetical order
          
          // Check the result to make sure everything is organized correctly, if the array isn't showing properly then the output won't work
          
          // Show all products under their brand groups, in an unordered list for simplicity
          foreach($products_sorted as $brand_id => $brand_products):
  
              $brand = get_term( $brand_id, $taxonomy);
              $gap = '<hr class="x-gap" style="margin: 80px 0 0 0;">';
              
                  echo '<h2>' . $brand->name . '</h2>';
                  echo $gap;
                  
                  echo '<div class="tax-products">';
                      foreach ($brand_products as $product_id):
                          
                          $product_featured = get_the_post_thumbnail_url( $product_id, 'full' );
                          $product_default = get_field('default_product_image', 'option');
  
                          $flavour_row = get_field('flavours' ); // get all the rows
  
                          $product_title = get_the_title($product_id);
                          $product_link = get_the_permalink($product_id);
                          
                          echo '<div class="tax-product-item x-column x-sm x-1-3">';
                              if( $product_featured ) :
                                  echo '<a href="' . $product_link . '"><img class="tax-product-img" src="' . $product_featured . '" alt="' . $product_title . '" /></a>';
                              elseif ( $flavour_row ) :
                                  if (have_rows('flavours')) :
                                      while (have_rows('flavours')) :
                                          the_row();
                                          // code here to show image
                                          $first_flavour = get_sub_field('flavour_image');
                                          echo '<a href="' . $product_link . '"><img class="tax-product-img" src="' . $first_flavour . '" alt="' . $product_title . '" /></a>';
                                          // exit loop after first image
                                      break;
                                    endwhile;
                                  endif;
                                  
                              else :
                                  echo '<a class="tax-product-default" href="' . $product_link . '"><img class="tax-product-img" src="' . $product_default . '" alt="' . $product_title . '" /></a>';
                              endif;
  
                              echo '<div class="tax-product-meta">';
                                  echo '<h6><a href="' . $product_link . '">' . $product_title . '</a></h6>';
                              echo '</div>'; // .tax-product-meta
                          echo '</div>'; // .tax-product-item
  
                      endforeach; // $brand_products product_id loop    
                  echo '</div>'; // .tax-products
              
          endforeach; // $products_sorted brand loop
  
      endif; // $products check
  ?>

  This is the page I’m working on.

  I have no idea why it’s grabbing the image that it is, if you click on each product you’ll see the image I’m trying to grab for each, the first one in the carousel.

  The main part in the code is the elseif part.
