I have the same problem, too. This is the second bug for me today. First one was about the fragments of the amulets and i can't find the piece that Gauldurson carries. Quest marker shows deep undergrounds

Second one is about the Glories and Laments. I already cleaned out that place before and got the book before the quest started. Now, some guy from the College of Winterhold asked me to get it. I had the book with me but there was no dialogue line in speech. I went to the dungeon and found a chest that has a quest marker on top of it. I already took everything inside of the chest before starting the quest so... Marker is still there, book is still with me and the quest is with the.. i don't know. They are small bugs but second time in a day makes me angry of sorts. Seems like we shouldn't clear out any place before completing all quests.
