Problems with Italian language after the update

Maybe this is the wrong place to talk about this problem, but I’ll try anyway. With the new update the Italian version got mixed with several English words. For example:

First four words are fine, but then I have “Help” (instead of “Aiuto”) and “Options” (instead of “opzioni”).
An another example can be “back” instead of “indietro”. I mean, this is not a big problem, but before this evening everything was perfect for my language.
