Menu item titles appear some in Greek and some in English

I’ve just installed Scrivener on my laptop and the app displays all menu item titles some in Greek and some in English.

I’ve never seen this before. I am bilingual Eng/GRK/Eng . My desktop computer is back in the USA (where Scrivener works fine) and I am presently in Greece. Is this current anomaly due to my location?

But, again, can the app determine where I am located and generate this weird effect? Kinda creepy isn’t it?.. How can I fix it? And BTW the list of time zones you use does not/does not include Athens, GR. Why?

Many thanks…//
