Currently when you use Portfolio Team Filter or Workitem team Filter you are presented with a list of some active and some deactivated teams - but not all teams. It is a very strange mix and is very confusing and causing mistakes

"When you are using the Workitem Team filter and the Portfolio Item Team filter, they will return a list of all Teams defined in the system, regardless of whether they are active or not. Unfortunately, the application does not return a full list of all Teams in the system"

Only active teams should be shown and all active teams should be shown
