No products found does not work only the loader is shown

When there are no products in a category and I click on that filter the loader is shown and it animates forever and the message does not get shown that there are no products found. To recreate this you can go to the link and select a category from filters like boxing gloves and then select a brand from top like century because there are no products in the boxing gloves category of century the message should be “No products found” but only the loader is shown and it goes on forever.
