Fade Rift Bug

I am having an issue with the fade rift in Emerald Graves in front of Chateau D'onterre. I closed the rift before I entered the Chateau. I did the whole side quest and when I exited the Chateau, I see the marking for the fade rift still on my map and the quest log hasn't marked it as completed. Is there any way I can get that quest actually resolved?
