If it is only one project behaving this way I would consider making a fresh project and copy evrything over. One should not have to do this but in the past I've had to do this when a project became haunted,,, well it was Halloween!
What you can do is save each track as a template as well to speed things up. What ever is causing the Haunted drum track should be left behind..
Or how about this..
Insert a new midi track
Get the haunted drum track to show and copy past it to the new midi track.
