Network Interfaces - No data

Network Interfaces - No data

Hello,
 
Is there something that I need to do in order for my network interfaces to have rx and tx data for them?
 
I have discovered the card and they are both sitting there under the interfaces tab, however when I drill into each one all the data/graphs/etc that indicate the throughput are blank.
 
If I use the MibBrowser I can retrieve information (for example ifOutOctets.11:-->441473950 ifOutOctets.12:-->3148583049) but nothing is showing up in OpManager when I go into the NIC.
 
Any ideas?
 
Thanks in advance
Troy
