I believe there is a problem switching back from a pdf book to a photo book inLR book module when the book is over 240 pages. I created a photo book with standard paper that is 400 pages. When I exported a pdf copy to save it when I went back to photo book it truncated the book to 240 pages because it defaulted to premium luster paper. It does not ask what paper to use when doing the switch. Can I make the photo book paper selection default to standard?
