vRA 7.2 Reclamation Error System Exception

Dear All,..

I have just implemented vRA 7.2, created new tenant in addition to the default one & created a simply linked-clone blueprint.

also, connected vRA to DC as endpoint, vROps & NSX.

however, I can't see the VMs in Reclamation tab as shown in the attached picture.

instead, Error  System exception occurs .

also, I noticed I don't have (Tenant Machines) Tab. instead (Deployments) Tab shows up in its place !!

can someone help me with the Error & explain why I see Deployments tab instead of Tenant Machines tab please ?

Thanks in advanced.

Regards
