Troubleshooting Wireframe Display Issues with Your Sitemap Pages

general question regarding the Nav menu in the wireframe. I have created my sitemap, and then switch over to wireframe. But the wireframe Nav isn't showing any of my actual pages. Why would it not show the pages I just created and actually have? Seeing some random other pages is not remotely helpful. And it doesn't seem to let me change the wireframe design at all, how do I edit the Nav. Plus, the Nav is so jumpy I can't even tell the functionality its attempted to demonstrate. The rest of the wireframe seems to work ok so far. But the Nav is so bad. I must have something setup incorrectly.
