Description

Hey, I'm working on a mod pack and I decided to add this mod to it. It works great, until I started a new world to test choosing a starter kit. This happens every time I start a new world.
I have other mods that add GUIs, but I don't think they should affect this one.
The GUI is off center and much smaller.
My personal settings for GUI is Auto, if that matters.
Is there any way to fix this?

Here's a picture:
Unable to show mouse in screenshots for some reason. If I need a new one, let me know.
(yes, my description for the class is terrible)
