Hello,

The standard element works as it should, it adds one product into the cart on any page. You have configured the products to be purchased, provided the buyer takes at least two products. By default, Woocommerce adds one product from the grid and any quantity from the product page. Please contact our partners for the customization, if you need to change it. It is quite complicated customization and we do not have a quick snipped to provide.

Best Regards
