Main Menu Notifications Don't Go Away

Every time I go to the main menu, whether it’s after booting up my xbox or after finishing any kind of mission, I always get a notification that I’ve unlocked something. Occasionally this seems to make sense, since I can go into the customization menu and actually see what I’ve unlocked. However, since the first week the game was out, I’ve always had a notification for unlocked movies, and I know I’ve watched absolutely every single cinematic/cutscene both in MCC and on the Halo Channel. I’m assuming this is a low priority bug, but anyone else have the same issue? Anyone found a way to make the notification shut up?

Seems like no matter what I’m doing, somehow, somewhere, I’ve unlocked something. Trouble is I can never figure out what it is I’ve unlocked, leading to the above problem. A fix or improved layout for this system would be greatly appreciated.
