Hello,
Goods Movement for Reservation Allowed is missing as pointed out.
As reservation against the production order is system generated you can not change it in MB22.
Have done the confirmation with Clear all Open Reservation?
Executed confirmation for the corresponding operation with parameter "Final Confirmation", "Clear Open Reservations" in CO11N?
I would suggest cancel the confirmation and try the good issue again.
Best Regards,
