Addons not working for all toons

[SangFroid]

For some reason, I cannot get Npcscan and Atlas Fu to work on one of my toons, however it functions normally on my other characters on the same account. I have tried unclicking / clicking on the addon screen, but that did not fix the problem. I did notice that Npcscan text color is different than my other addons.

I have tried deleting and reinstalling with no luck. Any thoughts? Did I somehow disable those functions only for that one toon?
