NDIS 6 MUX IM driver OID_GEN_RCV_OK issue

I am currently porting a NDIS 5 MUX Intermediate driver to NDIS 6. The driver is working properly, but I cannot get the number of sent/received packets, for the virtual miniport, to update in the Network Connections Status dialog or in Task Manager. I am fully supporting the OID_GEN_XMIT_OK, OID_GEN_RCV_OK and OID_GEN_STATISTICS OID requests. I have verified that these OID requests are being received by my driver and that the proper values are being returned. I am testing my driver on Windows Server 2012 R2 Standard.

Does anyone have any suggestions on how I can further diagnose this problem? Should the number of sent/received packets update in Network Connections for a NDIS 6 MUX Intermediate driver?

Thanks in advance.
