Robert, Please get rid of the messed up headers before you submit books, and please don't base a rating of book quality on those messed up headers. Often, page headers are written in a different font and will not ocr well, as compared with the regular text. If you see recurring issues like 55 for ss, you can do a search for that combination and fix the problem before the book is uploaded. Validation really should be a quick process. Check for author, copyright and book integrity. It shouldn't involve tens of hours of laborious work to fix up messes that were left by folks who submitted the originals. Mary
