Polylang for multilingual property with Estatik

Hello,
I am developing a plugin to import property data in Estatic and we use Polylang for managing italian and english property (Italian is the main language).

When we define the post for an english property, we have problem with the element tag because although the language is set correctly, the tag are set with the main language by default.

Do you know why this happen and how can i solve this?

Thanks
