Hi, SingingDog
We checked situation of the two tracks. The certification files of these tracks can not be matched with the original audios, so they can not be proved. We suggest you check whether the exported file is wrong. You could provide the midi file of main melody track or the audio file of main instrument. Hope that helps.
Thanks – let me try and determine if that’s the issue. I an usually submitting 4 or 5 tracks together as a set, and using the longest track as the reference track.
