Another question.
I made Green color unavailable for S size in variable product
Why does it still appears in the search on Shop page when I filter Green & S size ?
Thank you very much for choosing our theme and for contacting us.
You can correct the files for the checkout in the Appearance > Customize > Woocommerce > Checkout, there are a few fields that you can disable or make not compulsory.
It seems you have made the green variation as the default, please provide your site admin access to the private area I will check closer.
