I tried to configure to appear more than one prefix in the chat following this tutorial: https://github.com/lucko/LuckPerms/wiki/Prefix-&-Suffix-Stacking

So I did following this code:

prefix: format: - "highest_on_track_prison" - "highest_on_track_donor" - "highest_on_track_staff" duplicates: first-only start-spacer: "" middle-spacer: " " end-spacer: ""

So my configuration file looks like this:

prefix { format = [ "highest_on_track_donator", "highest_on_track_rankup" ] duplicates = "first-only" start-spacer = "" middle-spacer = " " end-spacer = "" }

I did anything wrong?

I want that display in the chat something like: [MVP][Trainer]Player

But it's displaying just: [MVP]Player

Confirmed working during Discord conversation, issue lies with the chat plugin.
