Raid Window - Cure error messages

[Talidoo]

When in a raid and a raid members gets an icon stating they need to be cured, I am able to click it and cure it -- however, I also get message in one of my chat windows saying the command is not valid or not available.

I have edited it so all 6 sets think I'm a warden, but that doesn't seem to stop the text messages.

Any idea what these are or how to stop them?
