Where does your guild xp setting apply?

I didn't really know how to word the title, but what I mean is, if you set /gu xp 100 on one class, does that stay as 100 for other classes, or do you have a different guild xp setting for every class? I thought it was the latter, but the guild xp was at 100% on a class that's level 11, which I've definitely never done /gu xp 100 on, though it seemed to work as I thought other times, so I'm not sure.

 

The /gu xp command affects all classes, at least from experience on my end. I've had to disable it several times when going to level a lower class because the guild contribution amount persists across all classes.

Pretty sure this has been that way forever but if anyone has had a different experience then I'm curious to know how that worked.
