The sorted database and the screen shot are more out of sync than the last one, which helps understand (perhaps). The 650 seems to be displaying the books in reverse-time order. The latest book added is the one that is first in the list. This correctly predicts the order for all of the Grishams, Rowlings, and Tolkiens.
Unfortunately, there isn't much I can do about the Sony's idea of a date. If I change it, the sony will change it back.
In any event, sorting isn't useful. Delete the file I gave you and restore calibre back to normal. I will now look at automatic creation of collections by_author (actually, by title within author) and by_title
