I think my situation may have been complicated by the fact that before it would download the purchase it did the firmware upgrade? So other than that same issue except instead of deleting the "preview" book ...I like an idiot clicked on it and when the preview said "you have purchased a preview to purchase full version click here"....I did it...and purchased the book twice! It took three more syncs before it actually showed as a full book! Now there are two charges on my cc for the same book. Other than by a mistake why would I purchase the same book twice? I emailed Kobo but I have had terrible customer service in the past and my expectations are not too high.
