Hi @stefaaan ,
FYI, our plugin doesn’t support private or hidden products to be added as component subproducts for smart bundles/composite/grouped product. All subitems must be publicly published and purchasable for the main bundle/composite’s pricing and discount to work properly.
The display issue with the product gallery must be triggered by a conflict with the theme or template you’re using. Some themes are not fully optimized for WooCommerce. You can test this further by switching to a different theme from our team https://profiles.www.ads-software.com/wpclever/#content-themes or any WooCommerce specialized theme such as Storefront.
Best regards.
