PAM Admin is looking at the UI and the A2A License Counts. If they go into PAM UI >> Devices and filter on the Device Type of "A2A", they get a higher count that is listed in the PAM UI >> Credentials >> Manage A2A >> Clients
PAM Devices in the db uag.host table have the value of host.typeA2A =1 entry but the host.request_serverID was NULL.
This is observed when deleting a Device in the UI, that has an A2A v4.5.3 Client defined against it.
Please engage Privileged Access Management support by opening up a support case to investigate further.
