Shopping cart broken product link

I created a product and it available on the internet facing site https://xxx.frappecloud.com/all-item-groups/products/product1 and customer can add it to the shopping cart successfully

but when the users browse the “my cart” the list of items appears okay but the product name link assigned to https://xxx.frappecloud.com/product1

is there any way to fix it ?

another question is there any way to customize the product page to add link to my cart after adding an item ?
