Mixed languages in Evernote for Mac OS desktop

[Skilliard 0]

Hello,
I'm a new user and try to run Evernote in English language on my German language Mac OS. I found the relevant information on how to set Evernote to EN in my personal settings. It worked yesterday, but when I started my computer this morning the language displayed is a mix of German and English, but in my personal settings the language is still correctly set to English, so I can't even change that.
What to do? I can't set my system language to English.
