Custom Post Problem… Not All Published Posts are Visible!

We had a custom post developed, which allows me to add new posts that show up as expandable boxes in a table format. This has worked well… until now. On the page below, only 6 posts (the most recent) are visible, however, there are 14 published posts. How do I make them ALL visible?

In the meantime, I have added all of the posts to the drop-down menu, but I don’t think that is an adequate fix. I’d like my little boxes to work!
