6 Appliance Install Error "Host has no networks. Cannot Proceed with Install"

All, I am installing our first vSphere 6 appliance.

When I get to the network settings I need to "Choose Network" from the drop down but it is blank. I am attaching to 5.5 hosts usinvg N1KV. The hosts are working fine but I am thinking this is a N1KV issue?

Any thoughts on this error?

Thanks!
