not working with another plugin

Hi, we largely work with your free plugin since a few years, really good plugin, thank you very much!

Now we installed a new plugin that manage the pricing and discount of the product WooCommerce Dynamic Pricing and Discount Rules Plugin (flycart.org) BUT, like in this page https://www.cuchillalia.com/black-friday-2023/ where we use your filters with their shortcode to get all the discounted product, well, if you try to filter, the filter is not working. Other pages, like https://www.cuchillalia.com/categoria/cuchillos/jamoneros/filtros/marca/kai/ your filter is working great….

Probably we have to add new selectors? which ones? thank you very much
