Problem/Bug EZRanksLite Groupmanager problem

Hello, and thank you for taking the time to read my post. I am trying to set up a Prison Server using EZRanksLite, and I use group manager so something is going on. When it ranks up, it says you have ranked up but doesn't actually change your rank. I do not like PEX and I always use and have used GroupManager
My Plugins:
WorldEdit, TimTheEnchanter, Essentials, EssentialsChat, GroupManager, PrisonMain, PrisonSuite, Vault, EssentialsSpawn, Kits, Multiverse-Core, WorldGuard, QuickSell, ChestShop, EZRanksLite, CrateReloaded
What it says when you rank up:
nothing. It doesn't say anything about changing rank, it just tops you to spawn and does some firework thing and congratulates you.
Here is my EZrankslite config.yml

Here is my GroupManager ranks:

Code:

 B:
    default: false
    permissions: []
    inheritance: [A]
    info:
      build: false
      prefix: '&4[&6&lB&r&4]'
      suffix: ''

You don't do

Code:

   inheritance: [A]

You need to change it to:

Code:

 B:
    default: false
    permissions: []
    inheritance:
    - A
    info:
      build: false
      prefix: '&4[&6&lB&r&4]'
      suffix: ''

Also look through this: http://dev.bukkit.org/bukkit-plugins/ezrankslite/
Perhaps use the in-game commands to create the rank-up groups etc.
