Problem with Lvl 8 mission

Hi, I have a problem on Metin2.US. I have lvl 8 mission, kill 3 hungry blue wolves, and I kill those all the time but cant complete the mission. What should I do?

ah this is because you have accepted another quest at the old lady u need to go and refuse the quest from her (i think its the old lady)

you're killing the wrong wolves. Keep searching them
