Cancel the discID delete. The disc is one solid thing you can be certain of.
Then edit the track list to fit what you hear. Also add an annotation explaining that “Track list as printed is wrong. When listened to by ear track 6 is blah and track 7 is whotsit”. Also make sure the Recordings linked have the correct name as you hear them after you do your edits.
This is not unusual. I’ve seen this happen on many occasions.
