Communication Manager that was removed earlier, reappears on System Manager web console.
Cause of the issue
In System Manager, the problem occurs when:
Two Communication Manager systems with the same name exist.
Out of the two Communication Manager systems, you manually add one system and the other system gets added from Services > Inventory > Inventory Management > Collect Inventory.
You remove the two Communication Manager systems.
The system removes the entry of Communication Manager from Services > Inventory > Manage Elements. However, System Manager still displays the two Communication Manager voice systems on the Services > Inventory > Synchronization > Communication System page.
