ESXi only seeing single NIC with M710HD blade NPAR NIC partition configured

Have some older M710HD blades that were retired from production and currently redeploying as a sandbox environment.  Since they were a big behind, all the firmwaer was updated on them including the NIC (Broadcom BCM57712).  An older version of ESXi was running on them previously with 2 NIC's partitioned for a total of 8 virtual ports.  Reinstalled them with a later version of ESXi, and about half the blades are showing the 8 virtual ports, but the other half only show 2 NIC's and are not recognizing the NIC partition settings.

I suspected the FW upgrades might have wiped the NIC configuration.  But going into the Broadcom NIC BIOS (CTRL+S) and the multi-function node shows the NIC is already configured for NPAR.  Also went into the UCS menu which also shows the same settings. 

What am I missing?
