Custom Song track looping problem

Thanks to Gi Nattak's tutorial and Xenovant's Midi2mml app. I manage to create a custom song and place it over the normal battle theme. The song plays fine, but when it loops, one of the track, which normally starts playing at the middle of the song,doesn't loop properly and goes out of sync with the entire song by start playing early. 
How can i prevent a track from going out of sync?
Here is the mml data of the problematical track:
