I have received a Amazon KDP proof of my printed paperback book. I followed instructions on youtube on how to format a book for KDP that is 5.5 X 8.5 I used mirror margins on the document. The problem is (I hope I am understanding this maybe I am not talking about mirror margins) the first page which is the the title of the book and the author name and the dedication page are left justified a bit due to I think the mirror margins. I'm not sure. How would I remedy this? I also have noticed that the odd pages, the pages on the are on the right side of the are just a bit hard to read that are close to the spine. I think I need to increase the margins there a very small amount. How would I do this?
