It is because the save template you were using was generating the same file name for multiple books. The default save template is "{author_sort}/{title} - {authors}" which will only have problems if you have duplicate books in the library. A surprisingly common (to me anyway) mistake is to change the template to something that uses the series name but not the title or series index. So using "{author_sort}/{series} - {authors}" would generate the same file name for each book in the series. And the result would be that you would have only one book from each series on the device. As Kovid has suggested, using the id field as part of the save template should solve any issues.


And note, your original post did not give any clue that you were talking about sending books to the device. It sounded like you were adding books to calibre, which is what prompted Kovid's original response.
