@jpj2k, there appear to be problems with the playback template, which I reapplied from here Organteq with Dorico - #35 by JesterMusician
This solved some but not all of the problems. Reapplying the template required once again deleting the extra instances of Organteq 2, ensuring the VST instrument and expression maps both said “Organteq 2” for each of the channels and then resetting the channel numbers to match what you sent. There still seemed to be some difficulties, though, so I then deleted and re-added the same stops and then everything worked fine. You might want to try a second similar project after re-installing the playback template. Also, you might want to refer to my revised Organteq 2 “recipe book” posted here earlier today.

Sorry I can’t be more specific about the ultimate cause but hope this helps. My revision to your project is here:
