Massive X performer starting from random positions

Hi,

Using the remote octave to trigger a Massive X performer while playing my project (the trigger note is written into the MIDI region) causes the pattern to begin somewhere near the end, instead of from the 'start' marker.

When I trigger the note manually using my controller, it starts from the right place.

My forehead is starting to wear a hole in my wall. Any help would be greatly appreciated.

Thanks.

EDIT: When I let my project run through an entire play through, then loop, the trigger suddenly kicks in at the right place. This definitely isn't intended, and means I can't play my project back from the beginning. Tf?
