I can't seem to find reference to this error anymore, I get the about error when i try to add it to a protection group, the vms is replicated from the protection site so I don't know its issues. Have an SR open but no fix yet
Operation Error: The VM is not replicated from the protection site VRM server (unknown) to the recovery site VRM server (unknown).
This ended up being an issue because we had to replace the vSphere replication appliances and the first VMware tech on the SR did not explain that would break the protection groups. If you replace replication appliances you basically need to recreate everything in srm, so make sure you get a config export before then so you can reimport it after you delete everything
