[Resolved] I got a different "published date" for the original post and its translations

I've created some posts in my default language (italian) and I've translated them in english. Then I've changed the "published date" for those posts in italian and I've updated the translation because I wanted the "published date" changed also in english.
But in english the "published date" was not updated, so I got a different "published date" for the original post and its translations. I need to have the same published date.
