Hello,

I see a variable product on your site with sizes and attributes.

I provided you the documentation of Woocommerce on how to create a variable product. Adding color/size is effected in the same way. Here is the documentation: https://docs.woocommerce.com/document/variable-product/

Enter the variable product: find the attribute tab https://gyazo.com/fe9a96c84c486866683f5725e5f281ae select all and delete those you do not need.

Then enter the variations tab and create the variations from all the attributes https://gyazo.com/8b3bcbf69f486d8d87f78ee62ce28d6e

I have tested and it works https://prnt.sc/pne8wm

Please clarify the problem, if any.

Best Regards
