Here's an example. I already bought Literary Introductions to the Books of the Bible by Leland Ryken when it was available only as an eBook.
It is now offered on Logos.com as well, in what I can only assume is a Logos edition. Previously whenever this happened, people who already owned the eBook would automatically get upgraded to the Logos edition. But it is showing that I don't own it.

It would be very easy to accidentally re-purchase a book that I already owned because of this problem.
