Problem with Plugin Polylang

Hallo
could you help me?

My site theme is Sydney and I use for translation the plugin Polylang.
All the site’s pages have been translated properly except for the front page and another page where I used the page builder.

I think there are problems between Polylang and page builder.
when I edit content using the page builder is changed in all languages.

when I edit something in Italian page it is also automatically modified in English version.
Could you help me please?

Many Thnaks
Michele
