Why are only two of my calendars showing up?

I really want to like Today, but its not actually working for me. I'm using the 7 day trial, on my first day, and even with all 6 of my calendars selected to be shown, only 2 are actually showing up. I was wondering if it was a limitation of the 7 day demo, so I tried different configurations such as one calendar selected that hadn't been showing, but no matter how I change it, I can't get certain calendars to show up.

How do I fix this? I was going to buy it if I liked it, but it has to work first...
