Content Editor

I am working on a redesign and in the process of copying the New Content from the redesign instance into the live site instance. I have already ported over all the new website files via FTP and parsed the layouts. The issue I am coming across is that the page template options within the Content Editor are not matching up with the new theme which is Aviato, so I can’t reconstruct the pages.
The only thing that comes to my mind is a caching issue? Please help!
