menu doesn't show translation

Hi Alessandro,
When I click on the flag to set the language on my website it doesn’t translate the menu in english and it shows only the italian (original) version. In the menu settings page I set it as both italian and english. If I create a custom menu it works but on some objects it shows the original name of the page. Did I do something wrong or is it a bug? I think it worked properly with an older version of the plugin, I’m not sure since it’s been a month since I’ve been working on this specific website.
