When I create my product page it is not full width (see image below):

However, when I link this to the product category, the product category then becomes full width (see image below):

How to I change this so that the product category is the exact same as the product page I create?

I still wannt my slider (the one that says chicken & poultry at the top) but I want the products to have the margins on either side.
