Most basic question - new scoutmaster

Hi. I’m new TroopTrack ‘adminstrator.’ for 3123. Super basic question: We have a new scoutmaster. I put an end-date on the former one, and added the scoutmaster leadership role to the new one (with the same start date as end date for former one). But it doesn’t show up in the ‘header’ when log onto TroopTrack. Is there a timelag, or is there somewhere else I need to flag the change?
