Hi all! I'm an old user for Calibre! Sorry my poon english, first at all :/
Sometimes, when i assign a number to a book that is part of a series or saga, the program doesn't show it in order. I try to upload a screenshot so you can make an idea of what im talking about.

As you can see in the pic, the number 5 book, its at top, and i cant find a way to get those books in order (from 1 to 5).
I first select "title" order, then "series" and then "author". Never had a problem before, always got the right order, except now

All the fields in book properties are well filled (same author and series). Any idea?
