Language/Region shenanigans - M365 Admin Center

Alright this is driving me crazy and I need help figuring it out. Google is failing me.

Basically last week I noticed in the attributes of my AD acct my 'co' was listed as Ukraine, though my 'c' was correct as US. Tried to figure out what, brain moved on. Today I noticed in the MS Admin Center (hybrid environment) when I went to different sections it would have a different language in the tab title. So instead of 'Home - Microsoft 365 admin center' it says 'Pocetak - Microsoft 365 admin center', etc. Everything in the actual site itself is correctly in English, it's just this tab title that is incorrect.

I manually changed the AD attribute from 'Ukraine' to 'United States' and waited for it to sync, but still does this. I checked my language/region settings in the gear icon on the admin center and they are all English and US.

Does anyone have any idea what might be causing this?

edit: Holy shit I didn't expect all the replies confirming the same issue. **Hopefully** it's just a dumb backend goof and not something more nefarious. Maybe it's my fault because I was set to Ukraine somehow. Sorry D:
