calendar Issues

[Avonlea22]

I tried adding a recurring event to my calendar.

Under Admin option, it states this:
"Click on which groups can see this event (Admin group always selected), or leave alone so all groups can see this event.
Multiple group selection allowed"

When I choose nothing, I can't see the recurring event on my board index. If I choose all users, I can see it.
According to the statement above, Admins should always be able to see the events, right? Or is this not the case for the board index? Just the calendar view.
