Translate header text on the front page

Hi again,

I am translating my website with Polylang and everything is fine except translation of header text on the front page. Unfortunately, I can’t do it in String translation as I would be able to, according to the tutorial.

Found similar post on this topic here on the forum. Is there any news about Polylang update so that it would be fully compatible and header text would be also translatable? I am using version 1.8.

Looking forward for your response!
