I migrated to distributed virtual switches, but some of the VMs now list 2 networks for their NICs. One in the old standard switch port group and one in the new distributed port group. When I go to "Edit Settings" on the VM, there is only 1 NIC and it is connected to the new vDS port group, but in the summary view, it still shows both. It has done this on a few of the VMs I migrated, but there doesn't seem to be anything in common. Any ideas how to get rid of the old network?
Please check, is there any snapshots on Problematic VMs.
If there is a snapshot, You need to remove it. It will automatically remove old standard switch Port group settings.
