PvP permanently enabled in capitals of my own faction

Hello!

I started playing WoW just recently, and I think I encountered a bug. I already talked about it to some people, but they don't really know what's going on either. No idea how to even look for it.

I completed the death knight questchain that had me talk to the king in stormwind and now I'm revered with Stormwind. But for some reason, my character is always flagged for PvP in alliance capitals, even though PvP is set to disabled. It also takes 20 seconds to log out for some reason.

Has anyone else encountered this issue? I have no idea how to fix this :x

Greetings!
