Team filter checkboxes are in a logical AND instead of an OR

I'm trying to set up the "Abscence Timeline" view with my dept. employees and all managers from other departments. In order to show this I select "My direct reports" and "Managers" checkboxes in the "Team" filter. All other filters clear.

With that configuration I only get myself as a result.

On the other hand if I select only "My direct reports" or only "Managers" checkboxes I get the expected result. A list with employees within that "Team".

It seems that the filter is doing a logical AND with the checkboxes selected, when it should be and OR and show both results.
