Phantom Story Updates

How Do I remove phantom story update notices? I watch quite a few stories for updates but sometime I get a notice of a new update when there isn't one! The last one was there for a MONTH until I deleted the entire bookshelf. Now I've got another one. I checked every story I am watching, no updates, I even moved a bunch that changed their completion status. Is there any way to delete this niggling little phantom update short of deleting the whole book shelf again!?
