Difference between shelf "All" and other shelves

[Anna]

I have a question about difference between sum of books on my shelf "All" and my basic shelves (read, currently-reading, to-read and twilight-series). Difference is like over 40 books. Other person in Poland group has the same problem. Combined amount of books from basic shelves don't equal the amount from "All" shelf. Why is that?
