I think you misunderstood. It shows the overdue count (in red) if there are any overdue actions. If there are no overdue actions, it shows the due soon count (in orange), if there are any due soon actions. If there are no due soon actions, it shows the inbox count (in gray), if there are any inbox actions. It only shows 1 number, the "most critical" number if you want to think of it that way.
