Filter Pro + Polylang Pro not working

Hello,

We found a bug that Filter Pro module is not working with Polylang Pro module.

1. Polylang + Woo = Ok
2. Filter + Woo = Ok
3. Filter, Polylang, Woo – Not working

Tested on clean version. After we change WooCommerce payments or any settings, we get permalink issues and a blank page, for pages, not for the homepage, that is template or woocommerce pages, but only for pages. After we resave permalinks, all goes ok. But when even we change any setting on WordPress, we get the same, empty page, like the page does not exist, not 404 but only Header and Foter. In some Local tests, we tested some previus versions of Poly and Filter, work fine, but only on local, when we do the same of Target page, where the problem existing, again we get the same broken pages.

Better to repeat this issue is on clean WP. WP + Latest Polylang Pro with 2 languages, all standard settings for hiding languages.

And one more note: If we allow that default language does not remove lang code from url, then all filters and poly work fine.
