Thank you for raising this question, there was some issue that made deletes a bit less reliable, fixed now. I see you've deleted 5 sites and no longer see them in your admin panel.

It's still possible they could appear there occasionally - this could happen if some relays haven't received/processed our deletion requests, and then if we failed to load all deletion requests when loading your sites due to relay timeouts etc. That's the way nostr works, we'll see if there is anything we could do to improve it further.
