Hi, Im using the latest version of luck perms and essentialsX chat version 2.18.

My issue is when I've tried to stack prefixes it just wont show up.
luck perms prefix config:

essentialsX chat:

Image of what is showing in chat:

where as it should be:
[B] [Owner] M1st3rminecraft: hello world

Looks like wrong indentation, it should be something like:

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

thanks :)
