DCTL missing - popups

In v19 and now in 20 I'm constantly getting popups about a missing DCTL. It's one I had loaded previously. I deleted it from my files in explorer and updated the list. It doesn't show in my DCTL node. I can't find any system cache that it might be looking at. I've rebooted several times.
