Problem with Woostify Filter | WordPress.org

Hello,

I have a website with a shop and I am having the following problem when filtering my products.

When I go to https://www.pipalook.com/categoria-producto/nuevo/ to buy products, and filter either by size, category, etc. When I reload the page, all the filtered products disappear except the ones I have selected and I mix products that I have in buy with rental, then the user can be buying a product that is really a rental and it is a serious problem.

The rental link is this one:
https://www.pipalook.com/alquilar/

I have been looking at everything to solve this, but it seems to be an internal problem of the plugin, thanks in advance, I hope your answer.
