Theme Test Drive Plug-in major issue in Page Atributes

Hello,
Totally New to WP. Familiar with html & css. This is my first time using CMS & a theme. I have installed this theme as a test theme to work on while another theme is what the public sees. Along with this plug-in that allows all of this to happen
My issue is that my permanent theme has features such as 4 different template pages, that my temporary theme does not. I am unable to see these template choices & their drop down menu in the Page Attributes sidebar of the all pages tab, when the theme testdrive plug-in is being used to work on my permanent theme. If I deactivate the plug-in I can see the drop down menu, but deactivation defeats my purpose. Site is Is there a work around for this issue, maybe putting the permanent theme in a sub directory, not sure how this would work for wordpress?
Thank you kindly,
Stacey
