Can you check if Caption is available on the DB (use DB Manager on primary)? Try running the below command to check if Caption is populating the Node Name
SELECT Caption,IP_Address FROM Nodes where IP_Address like '10.208.147.65'
If Caption lists the IP and not Node Name , try re-adding the node and check the same on DB again
Hope it helps
What field name are you using for 'Node Name' in your report ?
