I have a lot of books & many are part of a series of 10 or more books
I have tried to number the books from,say 1-28 in the title column and also in the series column,in these columns the books appear in the correct numerical order.
When I try to send the books to my Amazon fire HD10 the series numbers are out of sequence (eg 1,10,13,15,instead of 1,2,3,4,5 & so on.

I have even put the book covers on to paint,added a text box at the bottom of the book cover & tried to send the books to my device in the correct numerical order,but it still jumbles them up.
I have tried every way that I can think of to make the books appear in the correct order & now am completely stuck.

Has anybody solved this really annoying problem? if you have,please enlighten me & tell me how you did it.
Thanks in advance
