Violet is Blue Too not completing

Hi all,

Getting very confused....I've done all the steps in Violet is Blue Too quest and received the rewards, but I didn't click complete in the complete dialog that popped up and now it shows as complete in the Quests Log/Overview/Journal but there doesn't seem to be a way to close it out....is there a way to bring that quest complete dialog back so i can click complete there, seems like the only way to actually close it out....
