Language change-dialog is taking the wrong language

after the attempt to fix of de-sync issue #780 (closed) the displayed language is OK.. on my case.. Italian... but when i open the Language change settings is displayed 'English" .. and there are no more options if i want to change language i have to select a FALL BACK LANGUAGE (the same as displayed on first button... ENGLISH)

ths issue is very simialr to : #747 (closed)

P.S. this is a regression... this was fixed with commit: 5aa1aea6

ALSO... the language is translated only on some parts... and is a mix of italian and english
