In Admin mode
Goto Action Plans-> Manage Action Plan
Click View to view a plans tasks
Check/uncheck the completed status of an action plan task
Click Show: Completed or Show:Uncompleted
(but don't click update)
the count of completed/uncompleted tasks doesn't change
IMHO when you click Show: Completed or Show:Uncompleted it should be the equivalent of clicking 'update' and the counts should get updated.
