Custom Post Type Meta Box Data Saving

I’ve created a custom post type for events modeled after this tutorial:

It works well except for one big issue. I added meta boxes for date, time, and location information on the side. After I enter in a new event, save it, and then go back to edit that event, the meta box information is there, but it’s displaying outside of the text field box.

This is my first attempt at a custom post type, so I’m really at a loss as to what’s happening here and how to fix it. Any help?

Here’s a screencap of what’s happening:
