Weird Problem? (Haha, now solved . . . )

Update: Never mind! I just read a different edition and accidentally reviewed a different edition! Completely my mistake! Sorry about that! :D

 

So, under the number of books that I have actually read, it says that I have read 150 books. And then under reviewed, it says that I have reviewed only 147. It should be 149 because there is one review I have yet to write! I've looked through all of my bookshelves again to see if I accidentally marked a book as read but nothing is there! I'm not exactly sure what book I haven't reviewed. Apparently I've read two extra.
