Page Numbering in Book

Hi,

I have a book with 3 files, the first file is meant to be front matter, and the other 2 files are Chapters. I am using the page numbering convention Page # of #.

Right now my front matter file is 2 pages, Chapter 1 is 2 pages, and Chapter 2 is 3 pages. I have set the page numbering as 1 for the front file, and the 2 chapters are set up to continue numbering from previous page, however the last page for each file is currently showing:

Front Matter: Page 2 of 2

Chapter 1: Page 4 of 4

Chapter 2: Page 7 of 7

What have I done wrong and what can I can do to fix it?

Thanks!
