Plugin Help PEX Prefix not working

Before anyone tries to suggest adding in another plugin to make it work:

I am trying out PEX for my permissions. I have been working with servers for a long time, always used PermissionsBukkit because it was quite simply, the only permissions plugin that worked for me 100% of the time. But now I am wanting to reach out and try PEX for the extras that it offers, so that I don't have to download more plugins to do what it can do.

Like prefixes. I would rather just use a permissions plugin that lets me set the prefixes to the ranks, so that it's all magically together. But I have found that this is... not working. I followed the examples given on the Wiki, and even just copied the damn config file as it is there, but sadly, still nothing shows up.

I see plenty of people saying "download this plugin for prefixes..." but the whole point of me using PEX is so I don't have to use a whole different plugin for the prefix. So, are there any solutions to PEX actually making prefixes happen without having to add in another plugin?

 

Group Prefixes:/pex group (group) prefix '(prefix)'
Player Prefixes: /pex user (player) prefix '(prefix)'

Lemme know if that works out for you.

 

I already have the prefixes set up. They simply are not working.

Code:

groups:
  default:
    options:
      default: true
      prefix: '&0(&9Guest&0)&7 '      
      rank: '1000'
    permissions:
    - modifyworld.*
  Admin:
    permissions:
    - -modifyworld.mobtarget.*
    - modifyworld.*
    - permissions.*
    options:
      rank: '1'
      prefix: '&0(&4Admin&0)&7 '
  Master:
    options:
      rank: '100'
      prefix: '&0(&1Master&0)&7 '
  Creator:
    options:
      rank: '101'
      prefix: '&0(&2Creator&0)&7 '      
schema-version: 1
users:
  ea1fc847-20d5-3ad1-80ec-7f70d81ecc45:
    group:
    - Admin
    permissions:
    - permissions.*
    options:
      name: Xanadar
worlds:
    Gaia:
        inheritance:
        -Normal

 

@Xanadar You need a plugin that works with chat along with PermissionsEx. You can use ChatEx or EssentialsChat, something to that effect, and chat will format to how you set it.

EDIT: I know you said you don't want another plugin to have it work in chat but with pex you NEED another plugin that does chat for it to work. I highly recommend ChatEx if you don't want to add Essentials and EssentialsChat.
