Problem/Bug Group Manager HELP!

Hello Forums, Today I have a problem... My group manager rank Prefix's are not appearing when talking in chat. My permissions are working but when i talk in chat it does not show the prefix. I am using essentials Chat. Sometimes when my prefix's finally work it just works for one rank which is the butcher rank then when I /manuadd to another group the Prefix stays the same from the other group and the permissions change.


My groups.yml: http://pastebin.com/JDycCcar


Help Please!

It also maybe be the problem of an outdated essentialschat.jar if you guys would like to give me the 1.8 version

 

Googling "Essentials for 1.8" would've yielded this result, here you go: http://hub.spigotmc.org/jenkins/job/Spigot-Essentials/

Make sure to replace ALL of your Essentials plugins (Core, Chat, Spawn, etc). Current GroupManager is fine though
