attendance rolls not updating for next quarter

I have one class, Valiant 9, that is not populating for Q1 2023. All the other class rolls are updating. The members are shown on the rolls for Q4 2022. Any suggestions?
Thx, Larry Welling

How many Valilant 8 do you currently have in 2022 and where are these children showing on the rolls for 2023 if not in Valiant 9? Is it possible they were put into the current class manually at some point? If so, this could mess up automatic advancement. Suggest comparing all of the 2022 rolls vs 2023 and see if there is a clue or pattern there.
