((WPC Product Quantity for WooCommerce ))not work in cart page

I have a ((WPC Product Quantity for WooCommerce))
It works well on the product page, but on the card page, the product is returned to the default value and not the value you chose on the product page
For example, if I choose 100 pieces of the product on the product page, when I go to the card page, I see the default value that you put in the settings, not the value you chose on the product page
