Polylang and Easy Property Listings Search

Hello and thank you for this great plugin, that we use for a long time.

But recently we can’t make it work with Easy Property Listings Search. EPL Search loads default language results, not the actual language.

However then, if we click the flag, it loads what we need, but sure it’s not the good way.

Anyone knows where to look for a problem?

Settings:
The language is set from the directory name in pretty permalinks
