Polylang translation on custom post types

Hello,

Thank you for the very useful plugin.
I am trying to test an implementation of Polylang and FilterEverything on a custom post type. Unfortunately, I don’t have an online example to show, so I will try to explain what happens here below.
Currently, when I go the archive page of the custom post type (in the main language) I can filter the posts as expected using the widget. However, if I go to a translated version of the archive page the widget doesn’t show the expected values (I am using a range field on a custom field). It looks like a problem of the widget, as the search parameter in the url (e.g. mylanguage/mycustompostype/?min_myparameter=999) works as expected and can filter the custom post types. Note that I have tried both with the widget for all languages and one for a specific language, but the result is the same.

Do you have any suggestions to solve this problem?

Thank you,

Giuseppe
