Existing Absences showing more employees than direct and indirect reports

Summary:

Existing Absences showing more employees than direct and indirect reports.

Content (please ensure you mask any confidential information):

When we access My Team > Quick Actions > Existing Absences, I see the direct reports for the line manager I'm logged into as. When I unselect Direct reports in the filters, I can then see employees outside their direct and non-direct reports. Why would this page show more employees outside of their team? We're used to pages showing just their immediate team or people within their AOR. This employee I'm viewing doesn't have any AOR's so I would expect his pages to just show his team.
