Agent Server not reflecting under "Add Group" or " Add Object in SCOM 2012

Hi,

Here the Windows Agent server are showing healthy under 'Windows Computer' in Monitoring tab. Also I can view the various objects  like Memory, Logical Disks, System etc under Performance View. Once I moved to Reporing tab, I cannot find this agent server under Add Group or Add Object.

I tried reconfigure the SCOM agent on this server and still no luck.

Could some one pls assist me to resolve this issue.

Here the Management server is SCOM 2012.

Thanks
