How to keep the Checkout empty after check out finish

Hello,
AFter checking out and pay it's done, the pictures of items and categories come listed see attachment how I can remove or not being listed, thanks

Hello Nick and thank you for the solution,
this part has been done, but the part I'm talking about that when click the checkout button on the main menu it gives you a random listing of mixed category and products, should it give the cart is empty because of no items
see the link below when I click on checkout button and there is nothing to check out that what happened,
the URL of the checkout change to this when you click on it,
marselspizzeria.com/hikashop-menu-for-pr...ting/product/listing

more additional information
so basically if I did not add to cart anything, and I clicked on cart button or checkout button that will show cart empty which is correct and random of items which is not correct, i would appreciate your help to guide me how to fix this, when you click the cart button or the checkout button and has nothing been added to cart then only shows the blue message cart is empty and nothing else, thanks

Works perfect, Thanks
