Hello, @Tal,
Thanks for the access. I have checked your issue in depth and found that the issue is not coming from our theme. I installed and activated the “Storefront” theme on your site and set the filters and found the same issue. The thing is that there is something wrong with WooCommerce and you have to contact the WooCommerce plugin support in order to solve your issue. Once it will work fine with the storefront theme it will work fine with our theme too.
I have made a video for you kindly watch it complete: https://streamable.com/5umhxs
