I've had multiple instances recently where talking to Alice (Bookstore interior, Ticker Square) after finishing the quest (animated books version, in most cases) to turn it in results in her initial conversation cycling through the usual "quest in progress" dialogue. Sometimes she needs to be spoken with more than once in order to actually present the dialogue and choices that match your having solved the problem downstairs and lead to quest completion.
Sometimes a separate issue, sometimes happening alongside this one, your dialogue options for turning in the quest will refer to an entirely different quest. I most often get this with doing the animated books version but having dialogue about the robbery version.
