Sounds you slipped in a copy of a configuration file that refers to the same machine identifier as your King(?) Kong server – resulting in Plex considering those to be the same server (despite different names)?!
See the last bullet point from the related Linux Tips - #7 by ChuckPa post:
Cloning from one to another:
- Make a backup image
- Transport it to the new system
- Restore the image
- Remember to decommission (delete) the old
Preferences.xmlfile else you’ll have two servers with the same name and ID.
