It appears that the plex.tv account which you are using now to post in here, has one server attached to it.
It has been seen 18 hours ago.
It is not shared with any other people.
But 3 other people have shared their servers with this account.
Since you also have a Plex Pass on this account, I think you want to settle on this one.
You will have to make sure that your own server is using this account as well.
Here is a procedure to make sure of that: https://support.plex.tv/articles/204281528-why-am-i-locked-out-of-server-settings-and-how-do-i-get-in/
Then you will have to open each of your Plex Client devices and apps and make sure that these are all signed into this plex account as well.
Each Plex client can be signed out of an account and into another one.
After that, you probably want to grant the fine people who have shared their servers with you, access to this server in return. By going to https://app.plex.tv/desktop#!/settings/users-sharing
Click on each user’s name, then ‘Shared Libraries’, ‘Edit’ and tick the libraries on your newly claimed server.
