Problem/Bug Essentials Chat Formatting Not Working.

Hello,

I am trying to make it so people win a rank can have a different colored chat than default players but it doesn't seem to be working. I am using PermissionsEx v1.23.3

Code:

    member: '{DISPLAYNAME}&7:&7 {MESSAGE}'
    hero: '{DISPLAYNAME}&7:&a {MESSAGE}'
    divine: '{DISPLAYNAME}&7:&b {MESSAGE}'
    god: '{DISPLAYNAME}&7:&c {MESSAGE}'
    overlord: '{DISPLAYNAME}&7:&d {MESSAGE}'
    immortal: '{DISPLAYNAME}&7:&e {MESSAGE}'
    helper: '{DISPLAYNAME}&7:&a {MESSAGE}'
    helper+: '{DISPLAYNAME}&7:&2 {MESSAGE}'
    jrmod: '{DISPLAYNAME}&7:&c {MESSAGE}'
    mod: '{DISPLAYNAME}&7:&c {MESSAGE}'
    srmod: '{DISPLAYNAME}&7:&c {MESSAGE}'
    admin: '{DISPLAYNAME}&4:&4 {MESSAGE}'

//in pex, member is default. (for extra info )
