Thanks for indicating the pages template you used.
What I suspect happened is that you have used the Chapter Page for the first page of your project, and that chapter page is being dupllicated on the preceding pages.
All is not lost, however, and here is how you can set it up to behave the way you want (and I am shocked that Apple did not do this, since the Chapter Page is the
beginning of a series of pages, it should not stand alone on it's own)
first, in a new project with the chapter page as your first page, add a second page of text only. (you will see that in the Add Pages)
Second, link these two pages by deleting the Section Break which has been added automatically to the end of the Chapter Page when it was first saved. This will join the two pages, and their text. You can confirm this is happening if you have 'Show Thumbnails' selected in the view menu.
Third, once those pages are confirmed to be linked in the thumbnails, click on the first of those pages and go to Format-Advanced-Capture Pages. It will ask you if you want to capture the first page only. Select
First 2 Pages
This will save a set of pages which will be added to your template. By changing this text as you flow from one page to another, you will continue with the characteristics of the second page on all preceding pages.
Save the templlate as a work template (or as a Pages document even) so you can begin with the various pages you want. Every time yuo need to add a new chapter, insert those pages and start typing, and it will behave the way you expected.
I hope that helps. If you encounter difficulty or want to know more about how this all works, use the iWork manual. It's a great resource, specially if you search through it in the pdf file. Then you can search for topics that you need help on.
