You need to create either an acf/pre_save_post or an acf/save_post filter. Since you’re using the built in acf/pre_save_post filter I would go with an acf/save_post filter.

add_action('acf/save_post', 'update_setups_2019_title');
function update_setups_2019_title($post_id) {
  if (get_post_type($post_id) != 'update_setups_2019') 
    // only run on your post type
    return;
  }
  // get the post
  $post = get_post($post_id);
  // update the post title
  $post->post_title = get_field('field-one').' '.get_field('field-two'); // etc..
  // correct the slug.. optional and I don't know that this is 100% correct
  $slug = sanitize_title($post->title);
  $post->post_name = wp_unique_post_slug($slug, $post->ID, $post->post_status, $post->post_type, $post->post_parent);
  // remove this filter to prevent infinite loop
  remove_filter('acf/save_post', 'update_setups_2019_title');
  // update the post
  wp_update_post($post);
  // re-add this filter
  add_action('acf/save_post', 'update_setups_2019_title');
}
