Windfury totem not working?

Got my lvl 60 recently and upgraded my spells. Then started working on Onyxia attunement. In the first instance (ubrs) it worked, I could see the buff on my group. In the next dungeon (rerunning the first) it stopped showing on my group. Stoneskin and grace of air were showing up fine. I tried to put windfury right in the feet of team mates, and no show.
This was two days ago. And again yesterday when doing the dragon kills, windfury still wasn’t working.
Anything I shoud do to “reset” the skill or is it a known bug atm?

Were there other shamans in the group? Someone could have been specced in improved windfury, thus overwriting your buff.
