Double-sided template has page 1 on the left !
This scanning/inspection message warns you that page number X of the scanned QuarkXPress file is based on a right-sided master, which can cause problems when combining this scanned template with others in a script.
Below is an example of what the page structure of such a document would look like (note how the document has facing pages with page 1 on the left):
The solution is, inside QuarkXPress, to go to the Layout -> Layout Properties menu, and remove the facing pages attribute as shown below:
(if the Facing Pages option is grayed-out (disabled), then make sure that you have deleted all facing pages master pages, and then try again).
You should usually, if not always use the above settings for the Layout Properties of a any template.
