You have been making changes to the cost of the book i.e., the number of keys needed and I have been undoing those changes.

Please note that the number of keys needed will always be 1 less than the number of chapters in the book as the first chapter of a book does not require a key. So if a book has 16 chapters, the cost would be 15 keys. Please stop editing the cost to a wrong value.
