Microsoft Outlook: How can I get rid of multiple levels in my TaskPad?

I'm new to using Microsoft Outlook. I was playing around with the TaskPad on the side of my calendar to see what I could do with it. Somehow, I screwed it up and neither my husband nor I can figure out how to fix it.

I had it so that my tasks were organized into categories, and under each category heading, there was a neat list with one line per task, including a check-box. I liked that.

Now, it says "Categories:" and list the name of the category, with a minus-sign button to the left, then indented underneath, it says "TaskPad:" and the name of the task, again with a minus-sign button, then indented under that there's another minus-sign button and it says "Complete:" and yes or no, then indented under that is a white box with the due date. I don't want this hierarchical structure! I don't know how I did it in the first place, and can't figure out how to get rid of it.
