The word "fight" is always colored as if it was a shaman name

[Thex-PiedDroit]

Hi!

It seems my addon has, at some point, registered the word "fight" as someone's name, and has since colored it blue everywhere, for years.
I have tried multiple times to clear the stored player data, find that word in the WTF folders, etc, but it will simply not stop.

I realize it's a very small annoyance but i'd really love to find a way to make it stop do that, if that's actually a name stored somewhere.
Would you be able to help with this please?
