Please explain your issue?

When doing essentials /nick, the name in tab updates fine. (using setting change-playerlist: true in essentials config.) but when doing /nick off, the nte prefix in tab dissapears and only the username is there (in the right color though). It's fixed when doing /nte reload.

How do you reproduce the issue?

Is there an error(s) in the console? Please use: https://pastebin.com

This sounds like essentials is setting the player list names to &fName.

I will check and see if Essentials has Custom nametag events we can listen to. However, I believe their functionality is intended to have this behavior.
