IA Calendar - Invite list not updated

That is correct, I do not see them in Add Individual and was seeing older members, cubs who crossed over last year, and no new member from this year.

HOWEVER I FIGURED IT OUT! This is my solution/workaround, if anyone else has this issue.

Going to the ADD UNIT/SUBUNIT drop down menu (not even selecting a new item, but just activating the drop down) appeared to refresh the Unit roster for the event and I was able to add everyone I was expecting to the old event.

Cheers, and thanks for all the quick responses here.
Stay well,
