unexpected results

The quest unexpected results gotten from Apprentice Mirveda, currently is bugged for me, no matter how many times I abandon it or relog or close game and re open it, it just spam says "Protect Apprentice Mirveda(Complete)" I can not talk to her to finish this quest at all afterwards, but it spam says that on mys creen to the point were I can't even play cause of how annoying it is. If I abandon the quest it just keeps saying it and as soon as I relog it instantly gives the quest back to me and keeps saying that "Protect Apprentice Mirveda(Complete)" How am I supposed to fix this?
