Walk Forward - Updating Book

I love Amazon Kindle's Report module, but not too happy about the steps I need to take to revise a duplicate content word entry and an extra space in a hyphenated word in them text of my book, Walk Forward.

Problem is that to fix the errors in the free part of the book, I can not go up to Amazon.com and just fix, as I did with the "Book Description", I have to redo in Open Office, convert to .mobi again, and send it through the Amazon grinder again. The steps seem to be overkill as all I need to do is fix a hyphenated word that has an extra space and delete a duplicate word!

I continue to Walk Forward m to uncover the secrets of ebook publishing! I love the picture of my Mom on the book's cover, hope you do to?
