Can't do Warrior secondary profession

Hi guys,
I'm a ranger and checking out the secondary professions. I managed to do most of the other secondary professions but when I get to the Warrior one (first quest), he sends me out to kill the Grawls. So I go out and kill them all with a bow. I return and the mission isn't completed. So I figured he said "kill them with the sword", so I switch to a sword and hack at them. After killing one, I go to the mission log and it says "6 Grawls remaining". I kill another one and its still "6 Grawls remaining". Am I missing something here? Can someone help me out? I tried killing them using the secondary warrior skills he gave me too and its doesnt work. Can someone help me out here? Thanks.
Sincerely,
MK

I think that you may be killing the wrong Grawls.

If this problem persists, please email [email protected] Or use the /bug command.

Maybe you are killing the wrong grawls... You have to kill the ones in the quest location.

Go a little further along the road/field. You need to kill the Grawl INVADERS not the regular Grawl and Grawl Shaman

Exactly right, I was attacking the wrong Grawl at first, but when I noticed the log not updating I checked the quest again, and the text specifically states to head along the road and kill the Grawl Invaders.
