Reserve unit did not submit CT papers correctly for RegF

[militarymominthemaking]

Hello! My son just started BMQ in St Jean. He was in the reserves and his CT broker emailed him just before the holidays and gave him release papers. Now St Jean is telling him he might need to go back to Reserves because his unit did not submit complete documents. Is this common? Should my son contact his CT broker? Hoping someone can give some guidance.
