Why don't I have any books to place on the pedestal for "At the Summit of Apocrypha"?

I'm on the last stage of At the Summit of Apocrypha, where supposedly the books collected during the previous chapters must be placed in the correct pedestals. However, upon interacting with any of the pedestals to select a book to place, the only option present is "None".
Even after reloading an older save and going through Waking Dreams again, this situation still occurs. What have I done wrong?
