How to delete Cluster Network 1 in Hyper-V cluster?

Hi folks!

So I added a few 10Gbe cards to our 4 node HV 2012 R2 cluster. I connected two of them to the switches and almost immediately I saw this weird "Cluster Network 1" show up in Failover Cluster Manager.

I have since then disconnected the network cables, but it still shows up and the event logs keep saying that "Cluster Network 1" has failed.

Is there a way to delete this "Cluster Network 1"? 

I have already set "Do not allow cluster network communication on this network". It is not used in the "Live Migration Settings".  Rebooted nodes. Why is it still there!!?? Pulling my hair out here! LOL.

PS: the closest I could find on the 'net is this old thread:
