Help with DPanelList

When trying to add items to my DPanelList this is what happens with the button. Not sure how to position it.

Here is my code: http://pastebin.com/UpmGZney

How can I get these buttons to position better?

The reason I’m using the DPanelList is so I can scroll. Because my jobs will go over the panel limit. But I’m running into issues and our great GMod wiki isn’t too helpful. So any help that you can provide would be greatly appreciated!
