Hello,
While it does some time take for this info to make it back to VC, I usually just restart the mgmt-vmware service on the host which refreshes the VC DB almost every time.
The exact syntax is.
service mgmt-vmware restart
If it remains incorrect I would investigate the upgrade logs on the host to ensure it was applied to all of the components.
