Reputation Bar - WoW TBC Classic

I’ve noticed recently that my Reputation “XP” Bar in TBC Classic seems to be bugged. When I log-in or /reload the bar shows no text, but the minute I open the character window, the text related to the reputation I am tracking (name, progress) “freezes” onto the reputation xp bar after I close the character window. /Reload will fix the issue until I open my character window again, and then the text freezes again. I can’t find anything in my settings that is causing this, I have tried /console XpBarText 0 & /reload, I have disabled my add ons, I have deleted my entire interface file and restarted the game to fix any corrupt files. Nothing is working.

It’s driving me totally insane, any help would be appreciated.

Thanks.
