I'm using Search and filter, Polylang and Custom post type UI plugins. I have a problem with the project's search in a specific language. The search form allow you to select category and location of the project. In default language all works fine so if I select the category "Design" and the location "Italy" it returns me the url

www.mysite/categories/design/?location=italy

In the italian page, for the same search, it returns me the same url instead of

www.mysite/it/categories/design-it/?location=italia

How can I fix this problem?
