Member appears on wrong Roll

[nicoletonks]

One of our Primary children turned 10 on Jan 1. Her membership record shows that she should be in Valiant 10, which is correct. She is appearing on the Valiant 9 attendance roll and not the Valiant 10. I cannot move her to her correct class, because everywhere except the roll shows that she is in Valiant 10. How can I correct this?
