I have two network interfaces I can't seem to delete out of Orion. They're old port channels on a pair of Nexus 7K's going out to a border router. They're not in List Resources, so I should be able to just click them and click Delete, which appears to work (goes through the motions) but when you check back, they're still there. I even checked back a day later, and there they are.
How can I get rid of these?
