That's an error with the buff frames. I'm not sure exactly how it is, but in some cases you can no longer remove buffs from yourself by right-clicking them. I think this is when you use just about any buff frame addon - from what I read on SBF's page just after the patch hit, they changed the way cancelling buffs works, effectively preventing addons from providing this feature.
