Bulk save not working correctly

I have 45 girls that are marked as attended an event. We have a custom award for this event. Only 25 or so of them are saving as having completed the award even though I set all 45 up to do so. I have tried to update the missing girls via the Record Progress (Bulk) and via the Calendar Record Progress options. I get the message that all the girls were updated, but their individual records do not reflect this.
