That's the thing, i did try to leave a handful of pages and finish a book on new rebirth and didn't get it
Assuming you didn't spend any level up points at all, then possibly this means you have to start the book from scratch- like finishing an edition in the previous rebirth and then completing the whole entire thing, from the start, without using any level up points
Either way, the achievements do so little and it gives you it once you finish them all regardless
