I suspect this is due to an older kepub conversion process as these are older releases from September 2011 or older. The specific books all have a preview ending in a hyperlink to the Kobo store. These are the books I have purchased with the error.

I'll post a more detailed list of all the previews I've seen with this error tomorrow. These errors are not present in the Kindle editions.
