Demo login screen stuck in arabic?

Hi Folks-
Just went to the main demo site
https://demo. openemr.io/openemr/interface/login/login.php?site=default
and saw it was in Arabic, which is fine, but the default language dropdown is missing; 1st pic below.
Went to the 2nd demo and got the ‘click path’ (just coined the term!) to English in the language dropdown in globals. Went back to the Arabic site, did it and ended up in… Serbia? (2nd pic). I was able to get to English only because the word for ‘English’ resembled the English word for English. If I had been looking for some other language, especially one using a non-latin alphabet, who knows where I’d have ended up?
The quickie world tour was fun but it occurred to me that the way this is working, it would be possible (even if not that likely) for all the demos to become inaccessible except to the ones who set it that way, until the next demo reboot.
Avez-vous un bon weekend but that’s the limit of my French- Harley
