I have some problems with the product tabs on the home page as well. It doesn’t ever find all products in the chosen category, and the number of found products depend on which sorting method I choose.
Example: If I choose to sort by name, show 8 products as a start and 4 for each load more. Maybe I get 6 products from start, 3 on the first load more, 4 on the next, and 2 on the third. For other sortings I only get one product shown etc. What is causing this?
