Test Items not appearing

I have made some test products for my store and they appear on the catalog page but they do not appear on either the individual product page or the individual category page even though i assigned each product a category. Furthermore if i click on the product in the catalog page the modal pops up and says product not found.
Theme: Journal3
Opencart Version 3.0.3.2

Why don't you contact journal team?

cause it seems to be more of a open cart issue then an issue with the theme
