Please explain your issue. How do you trigger it?

I have LuckPerms, Vault , and EssentialsChat handling groups, and each group has a perfix set.
Some of my users are getting the prefix correctly loaded in chat when writing, but it doesen't seem like NametagEdit is displaying it in the Tablist and/or on their username display.
this is a photo proof:

Are there any errors in the console? Please use: https://pastebin.com
Nope

I don't really know, for me and other users is not working. I have the prefix set correctly , and in fact it shows up in chat Using Vault and LuckPerms. Otherwise for other of them its showing up in TAB.

look for example at the first user, she has group Anubis set with LuckPerms and displays in chat correctly ,but not with TAB. And also my user, i had to set the prefix manually.
