In the scenario when a CSR is created without a WF (by email for example), the engineer has to change the CSR Type to get the proper WF then the queue and the assigned user.
From Stat client, changing the CSR Type the WF is filled but the queue is not changed or refreshed, so the Assigned user is not filled correctly showing an inactive user that also is not part of that queue.
From the Web Client, instead the behavior is correct. Changing the CSR Type the WF is properly filled and the Queue and Assigned user are blank forcing the user to select one and in this way the queue is refreshed showing the right users.
