[VM 3.2.1] Backend language mixed Italian/English

[ermes]

Good morning, with the last update of virtuemart i have had a problem with backend language. It's a mixed of italian and english language (see screenshot).
So i decided to reinstall joomla (3.7.0) in multilanguage mode (it/en) and virtuemart with italian language pack (i want the backend in itailan) but there is the same problem.
How can i fix it? Tnx a lot!

My config:
PHP 7
Joomla 3.7.0 (multilanguage it/en)
Virtuemart 3.2.1 (with last it-IT.com_virtuemart.zip installed)
