In trying to add an event to the calendar (campout) it is showing most (not all) leaders in duplicate when selecting invitees. Also it will not allow me to scroll down, only up through the list of names. Duplication is only showing for the leaders. The leaders are not duplicated outside of the calendar in the troop roster. I also tried to do the same activity with the feature extension turned off and the same thing still happened.
Also, I have access to several units as a Scoutmaster of a boy troop, an ASM of a girl troop and a Unit Commissioner. The behavior is happening across all the units.
