CMS Problems Creating New Pages

I have created a site using Site Sculptor, I have several main categories which have sub menu items, each of the main categories were defined as Template pages when defining the site to give me the ability to create new pages from them.

The Problem is when I create a new page from the Main Category page, it creates it but it does not really create it, If I preview the page it has the same url as the page I have created it from? then if I update the content within this newly created page it updates and then when I check the content on the page from which I created it, it has also changed, this is because it is the same page at the same URL?, the newly created page does not appear in the site directory it appears the only place it is in the admin panel, kind of weird.
Also it does not build this into the menu, I read a post on this which was posted in 2004 and got answered in 2008! with the response that it does not add the page to the menu and that you must update the menu.php file manually!

Anybody that has overcome a similar problem please can you get in touch, all comments are invited.
Thanks
