If a Transports owner is changed in the backend SAP it does not show this update in AC. But AC will update if a new Transport Task is created or objects in the Task are changed in the SAP backend.
This is the intended design of Active Control, where the Transport Form Owner can be different from the SAP backend Transport Request owner.
If you want to see the actual SAP Transport owner you do so in the Transport Request Properties screen in both Windows and Web UIs. In these popup screens, they do reflect any SAP transport owner changes.
The Transport Form owner can be different though, this is why we have functions like "Forward" in Active Control, so other people can be given ownership of the Transport Form.

And this is how it can be seen in Win Gui Active Control Transport Form Properties:
We can see this Transport has changed Owner to RN_TEST
And in the WEB UI (Transport Properties) we can see that it also shows the new Owner
