Friendly name in Plex

Hello propellerheads! My nas server took a dump, I upgraded to truenas scale to run plex, (amongst other apps). I installed new Plex to the server and all is well but somehow the old plex server “friendly name” remains. When I set plex up this last time I used a different “friendly name” and I think it’s creating a conflict.

I’ve been trying to change “friendly name” and having a difficult time. I want to either reuse the old name or delete it and use the new name, whatever works. I got a warning in powershell that not using the GUI might create problems. I’m stuck.
