here's what i'm doing.
i have a pdf file that i want to make into a book.
i upload it, and provide a separate image for the cover. full wrap-around image.
when i get to the next page, it shows me the first and last pages of my book as the cover. oops, somehow it lost my separate image.
i then re-upload the cover image page, and it shows as the cover.
but it's lost the first and last pages of my book.
what's going on here?
