ENGLISH VERSION, BUT MIDDLE EASTERN FEAUTURES ARE DEFAULT

Hello, 

Since a year my default settings skip every time to a Middle Eastern setting.

I have no clue why as I have installed the English version. 

I 1st noticed it in Indesign, but was able to swith it in the preferences–however sometimes it jumps back to Middle Eastern sometimes. Today I wanted to set a small text in Photoshop and again the Character settings display on Middle Eastern Feautures. I cannot find how or where to change in Photoshop and it drives me crazy. I never use Middle Eastern settings at all, so why all of a sudden this happens?
I even downloaded the app again, but didn't help.

Hope you can help me out here!
