I just opened my Calibre and wondering, why is some of the words displayed in Arabic? I'm using OS X and my default language is British English but my keyboard layout is US Extended.

I would attach some images but I don't know how to do that here.

upload images to imageshack and than link them here

go to preferences and change language from arabic to english. same happened to me for some reason.
