Pages '08 Grouping Thumbnails - Quick Q, need help!

Hi all

So in Pages 08, I'm working on a 20+ page document, and the thumbnails along the left edge of the screen has grouped certain pages together so that when I select one, multiple above and below are also encircled in a yellow bar. The problem here is I can't re-order the pages without dragging 4 pages at once, and I can't drop a new page into the middle of a group.

How do I get rid of this grouping so each page is individual?

thanks!!

 

For some reason that doesn't seem to be working. All my pages are layout pages, not text, and when I select a page (or any element within a page) and go to the insert menu, the "Section Break" option is grayed out.

What am I missing?

 

any more thoughts? Sorry to keep bumping this, but I have no idea what to do - they're all layout pages, but I can't reorder them because they're stuck in these 2-5 page sections.
