Hello,
Our theme suggests three types of filters:
1. Top filters, you need to add widgets into Shop filter is in Appearance > Widgets
2. Woocommerce and WoodMart attribute filters in the Shop page area in Appearance > Widgets
These two types of filters work only on shop and category pages.
We have developed and suggested the third type of filters for all who want to have filters on any other page not related to Woocommerce. So these filters are used just on any page. They would not work in the mega menu, in customized top filters and anywhere else, they are just for pages.
Here are the detailed instructions: https://xtemos.com/docs/woodmart/faq-guides/create-filters-form/
Remove the customization of the top filters and use the filter just in the page.
Best Regards
