WooCommerce Error

Hello Team,

Firstly,your theme is really wonderful.Kudos to you guys.

My concern is;

I am using your theme for my ecommerce store and have added few products to my shop page.

However,whenever i try to edit the existing products for adding certain color variations, my add to cart button gets disabled.

Secondly,whenever i am trying to add new product of the same brand,the filters on the right sidebar doesn’t search the product of the same brand.

Please help me !

Thanks!
