After deleted the item. I get "product display"

-- HikaShop version -- : 3.0.0
-- Joomla version -- : 3.6.5
-- PHP version -- : 5.6

When I delete an item in the cart and I remain with the empty cart, then I get the message that the cart is empy. Right But I also displayed "product category" . Why?
How can I avoid to see the write: "product category"
