Page Properties Problem in Corel Website Creator X5

I would like to exclude a page from navigation. The Problem is...the exclude from navigation text and the box to check are not on the page properties box like the one pictured here.

My page properties box looks similar to this one. It doesn't have the four folder looking things at the top like this one does. It has 3 (Page, View & Actions). and it also doesn't have the master border box.

It does have the following

Page name

Page title

Custom names

Page type

Page Status (done & don't publish)

Comments

Anyone have any idea why it is missing and how to remedy this problem? Thanks for any input.
