Hi Everyone,
We have a problem when we try to close/delete user session on the firewalls managed by Panorama
We have multiple FWs under Panorama

Issue:
Unable to close Admin (or any user) session (i.e. delete) as Panorama client on the managed Firewalls.
The same status using Panorama API, for example:
https://<Panorama_IP>/api/?type=op&cmd=<delete><admin-sessions><username>User_Name</username></admin-sessions></delete>&target=<FW_SerialNumber>
or
Using FW cli (direct cmd)
The operation succeeds according to response message but Panorama session as client with user name on the FWs are not deleted as expected.
for example we got the following message:

But the session is not being deleted at all, the same behavior using the FW directly via CLI 

Platforms:
Panorama (VM, v10.1.0)

Managed FWs:
VM-(v10.0.0)
VM-(cluster1, v10.1.0)
VM-(cluster1, v10.1.0)

VM-(cluster2, v10.0.0)
VM-(clsuter2, v10.0.0)

Is there anyone who can help in this matter?

Thanks
