Unfortunately I can't offer much to assist, except to mention that BiaB seems to handle a user-entered Melody a little differently to other tracks. I've also had issues copying parts of the Melody track, especially when it has some bars that have less beats than the other parts of the song. But this is not using the Medley Maker though.

Do all of your bars have the same number of beats?
