Not sure what you are trying to do. But from your photos the first thing I notice is you have no chords entered in the chord chart. When you picked this style you had the opportunity to select from one of two demo songs. Pick one of them and then try again with what ever you are trying to do...

Otherwise, with the chord chart populated, I just was able to select, modify or insert new Midi Supertrack with no issues.
