Why All Products Showing Out of Stock

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3

It looks like each time I update the site this does not work or something changed.

Anyway, the client suggested that I turned on the "Display out of stock products", but it's now showing all products as been out of stock.

If you look at the URL provided and you click on the FIRST item, you will notice that the add to cart is present so this item still have stock. So, I'm not sure what's happening now.

I have the following settings and please see attached pic of badge.

System > Display > Display out of stock products = "Yes"
Display > Content Menu > Product Listings > Display out of stock products = "Yes"

Thanks in advance!

Thanks nicolas.
