OpenManage: FC630 blades not associating with chassis group in manage -> devices

I have a batch of  FX2's populated with FC630's. Upon creating a Device Group for the chassis and configuring WSMAN credentials (same for CMC and iDRACS) via 'Chassis (CMC) Discovery – All Components', only the IOAs and CMC show up in manage -> devices under modular systems -> PowerEdge FX2. The blade servers do not associate with the chassis group in this view. 

All the FC630's appear under RAC devices and can be managed/recognized normally as individual servers, so i do not believe it is a WSMAN issue. 

FWIW, this new batch of FC630's somehow had older firmware (  2.40.40.40  ) On a separate  instance of OME, I have dozens of FX2's/FC630's that seem group the blade servers without issue (running v2.41.40.40 ).Updating the drac firmware to the latest version ( 2.50.50 ) did not resolve the issue on a test blade, so this does not appear to be firmware related. 

I am currently running OME (v2.3) on both instances...so I'm wondering if this is a configuration issue within this one particular instance of OME? Any help would be appreciated. Thanks!
