Help request

Problem
The player list (Tab) displays my username, ping, etc., but it doesn’t show my prefix, which is set by Luck Perms.

The prefix appears just fine in the chat but not in the player list. If I give myself a nickname with /nick, it does display in the player list as expected, but my prefix doesn’t.

change-displayname, change-playerlist, and add-prefix-in-playerlist are all set to true.

Screenshots

The number after my username is part of a scoreboard added by a datapack.

Please try it without any other plugins installed besides those listed in /ess version.

I didn’t think that the server log was relevant. Apologies.

I tried removing every plugin, datapack, and mod I had installed—except EssentialsX, EssentialsXChat, Vault, and LuckPerms—and I also created a new world. However, I’m still having the same issue, so it’s not a plugin conflict.

Here is the server log after this test.

After taking those screenshots, I also tried removing my active resource packs, but that didn’t change anything other than making the font look all pixelated again.

I also tried to set a custom join message including the display name of the player joining:
custom-join-message: "{PLAYER} &ejoined the game"

However, it just shows their name, not their prefix. For some reason, the prefix doesn’t seem to be counted as part of the person’s display name.

Change add-prefix-suffix: false back to true. When set to false, EssentialsX will never add the prefix/suffix to the player's display name, even when you set other options to true.
