I've looked through forum for about 15 minutes but didn't find any discussion of this. I have a couple of MIDI parts in two Utility tracks. If I delete measures in the chord sheet, the measures don't get deleted in the MIDI parts, so in this case they play late. Also if I copy/paste a group of measures, the MIDI part doesn't come along. Any options for enabling this?

Same here!

Many other problems with MIDI on Utility Tracks. One major one being that they don't transpose along with the main tracks when you change key of the song. At least this is the case when you copy/move the tracks over from the Melody Track, using Copy Special.
