I have this problems with 2 modules: tab slider and products tab.
When i choose my custom categories, the modules load always the same category (it seems a random category).
When i change the tab i see always the same products, like this i can’t customize the modules.
Its very strange because if in the settings i choose the “default” categories like featured products, special product, new product it loads the correct products. The problem occurs only with my categories.
