Remove undefined Zwave Nodes

Good afternoon,

About a month ago, about the time of the HA .115.3 release I tried getting my Schlage Zwave deadbolt to work, and totally messed up my whole zwave network. I’m in the process of removing all my entities (about 20) and starting over. I’ve restarted the system several times, but still have multiple undefined nodes showing up.

When I go to the Device screen they all show up.

I’ve used the Remove button to remove, and the button doesn’t show up anymore.

How do I completely remove/reset?

I’m 99% sure they are linear wd500z-1 dimmers.

Thank you all for any help.
