Hi, i accidently closed the ticket.
Still have this problem after switching and reinstalling theme. On the standard storefront this problem does not excist.
1) I have alot of products, but some are out of stock. I have the option “Hide out of stock products” on.
What happens now is that the products will indeed hide, but the quantity on the catalog page is different. For example: Standard page has to show 12 products, but it wont always show 12 products. I think this is due the theme seeing the hidden product. This is also an issue for the homepage blocks (to show products from the catalog on the homepage)
