Hi Marcin,

I'm so sorry for the late reply!

I added a snippet for you here https://www.screencast.com/t/2h2xIx46WH and it works fine now https://server167245.nazwa.pl/spawear/sklep/odziez-medyczna/damska/komplety-medyczne/komplet-medyczny-fartuch-diana-spodnie-unisex/

Added snippet for backup:

/* WPC Grouped Product - Fix variation gallery */
add_action( 'wp_footer', 'woosg_variation_gallery', 99 );
function woosg_variation_gallery() {
    ?>
    <script type="text/javascript">
      (function ($) {
        $(document).on('found_variation', function (e, t) {
          if ($(e['target']).closest('.woosg-product').length) {
            $(e['target']).closest('.variations_form').trigger('show_variation', [t]);
          }
        })
      })(jQuery)
    </script>
    <?php
