How to delete zombie config nodes

I deleted some config nodes while doing some development and testing, but according to the log, they still exist. They're not listed in the configuration nodes display and they don't go away when I restart node red. How do I delete these?

What version of Node-RED are you using?

Whoops. Hold on. I think I may be wrong.

Restarting node red does clean them up. I was wrong. Sorry for the confusion.
