Print Permission Slip showing all events

If I go to:

https://troop-252.trooptrack.com/plan/permission_slip

The Event dropdown lists all events for the next year (including adult leader meetings, troop meetings, your leader meetings). These events appear on the list even when the “Permission required” checkbox is UNCHECKED on the Advanced tab (https://troop-252.trooptrack.com/plan/events/624101/edit).

I’d like to remove these events from the list to prevent confusion. Is there a way to do that?

Thanks,
Nick

P.S. Keep up the great work. Our troop is working toward doing everything in TroopTrack.
