Alex,
I see what you mean.
I just imported a type 0 midi track to Melody with same results as you.
However, I noticed that the import Melody from Midi file “directed” the Midi to Utility Tracks not the Melody. The Midi can be seen on the Utility Tracks in notation. Can you check if this is what happened on your end.
