Checkout menu item unusual display

I have a user menu with the checkout as one of the menu items. When there is something in the cart it displays the cart contents correctly but if the cart is empty it displays the empty cart message but displays 'Categories' below that. Should it not just dispaly the empty cart message on its own.

Ok, Thank You.
It might be worth considering that if this field is empty that it returns nothing except the 'Empty Cart' message
