Work Order Tasks are not being displayed on the task panel on FSM Dispatcher Workspace

[Damayanti Sarod]

On the FSM Dispatcher Workspace, the Work Order Tasks are not being displayed on the task panel. We impersonated a dispatch group user, selected their associated territory on the Dispatcher Workspace, but the task panel still does not show any Work Order Task cards.
Its working in PDI, but not on client instance.

Please refer to the snapshot below from the PDI instance, where the task cards are visible.
PDI: Zurich Patch 5
Our instance: Zurich Patch 6
