One group doesn't send calendar notices #cal-notice

Karen Ivy

I have 2 groups that I tried to set up identically.  Each one has calendar entries for a bimonthly event, which should go out 5 days before the event, and again 2 days before.  As administrator I have accounts on both and should get all notices as individual emails.  Yesterday the smaller group sent out a notice but the larger group didn't.  Any idea what I did wrong?
