Deleted a reusable external action from test, but the Action Filter and Local Datasheet still does not reflect the removal from the test.

We have discovered that when a Re-usable external action is called into the main test and then is deleted, the main test will delete the call to the action; however, the test flow filter still contains the external action in the list of external actions in the main test, as well as the Local Datasheet remaining part of the test.
