Hey Erik,
It is CSCua93737: Port-channel has Ghost entries even after removing ports from N1K setup
You can view the defect using this link

Workaround:
1. Create a new port-profile and associate new uplink interface to it.
2. Associate active ports to the new port-profile so that there is a new port-channel created with active uplink ports.
3. Delete the old port-channel so that all the ghost interfaces would be removed along with it. If you wish to use the same port-profile for all uplink ports, then you can move the uplink ports to the old port-profile one by one so that a new port-channel will be created using the same old port-profile.
The defect is resolved in SV2(1.1).
Thanks,
Joe
