Ok, I see what it is doing now. The import is not importing the template I created but rather exporting and importing the entire site.
I had a dev site that was blank except for Pro 6.4.12. I upgrade the site to Pro 6.4.13.
I then saved a section header from another site. I downloaded this header template and imported it into the new site.
The end result was that the entire site was imported into the site. The empty site now has everything that was in the site I created the export from. Except it doesn’t show any thing in the library.
In the site I was working on yesterday I now have double of everything …
