You can only choose to download 1 of the various formats after "purchase", so if you want to be able to download in another, you'll have to "re-buy" the book by adding it to your cart again.
Also, the checkout process has a lot of pages to go through, so keep clicking until you receive confirmation and can see the titles in your library.
