Hello,
Go to Appearance > Themes > install and activate default WooCommerce theme Storefront. Let me know if filters work fine with the default theme.
As we know WooCommerce filters never worked out of the Shop or WooCommerce archive page, probably you missed it in our previous answer. But if plugin that you use makes something that they work with default theme and you have problem with our theme only then we’ll be able to check. But if filters do not work even with the default Storefront theme then contact plugin author, we can do nothing.
Regards
