Oh, that's strange. Hmmm. Are there any other details you can tell me? This might be a bug in the editor. When did you start seeing the issue? After a specific operation? (sav,load,etc..) This is a big ask, and I'll understand if you don't have the time, but if you upload the SNG file for your song and send me a key I'll be more than glad to try debugging it to figure out what happened.
