annasta Filters disables the product categories lists of the main shop page and subcategories display of categories archive pages, because these lists are not supported by the filters.
Starting with version 1.5.5 of our plugin the Product categories / subcategories option has been introduced in the annasta Filters > Product lists > Add elements admin section. It provides the insertion of filterable categories/ subcategories lists via the standard WooCommerce hooks.
If you wish to disable the suppression, please go to the annasta Filters > Plugin settings admin tab, and disable the Force products display option.
