I’m going to try to help you by explaining what the problem with your code is. This comes up often because most people don’t understand how wp_reset_post_data() really works.

 
  // this is inside the main WP query loop or "The Loop"
  
  // some time later
  
              $post_object = get_sub_field('pick_the_dates');
                if( $post_object ):
                  $post = $post_object; setup_postdata( $post );
                  
  // some time later
                if( $venue_object ):
                  $venue = $venue_object;
                  
                  setup_postdata( $venue );
                  
  // some time later, 
  // this is the problem.
  // wp_reset_post_data does not take any arguments
  // this function, no matter how you call it will always
  // reset post data to "The Main Query"
  // once you do this, any reference to the post 
  // object returned by get_sub_field('pick_the_dates') 
  // will be looking at the post of the main query instead
  // of what you think you are looking at
  // in order to have multiple nestings you must use 
  // alternate means of getting values
  // other than using setup_postdata and wp_reset_postdata
                  
                  wp_reset_postdata( $venue );
                  
  // some time later
  // this next line actually does nothing 
  // because it was already done above
        
                  wp_reset_postdata();
