Bukkit

What is the issue?
     I've been making my own classes in the config, much the same as the ones in the original file (In fact, they all originally started as the other classes), and upon opening my server, the classes disappear and are replaced with your archer.
Please provide any additional information below.
     I run a Zelda themed server, so I was making classes that go with the theme (Kokiri, Goron, Gerudo, and Zora). I've made all of my classes using the specifications outlined in the original config with your pre-made classes. Being that the originals were not Zelda themed, they were re-named and changed slightly to fit the actual theme, generally running over the initial spaces provided (On Notepad ++, the added parts actually added are in red font). The result was that my classes are continually over-written by your archer and your archer is the only available class in-game. I was wondering if there's a problem, am I doing something wrong, or am I just dumb and I'm doing it completely wrong.

1. What version are you using? 2. Can you post your config to pastebin or something, and then post the link here?
