You're welcome on all accounts. :)

Excellent screen shots.

Looks like it is time to email them. There may be some sort of regional royalty pricing going on, but I believe it should always be the same based on what you put in the second screenshot where you chose 70%.

Might need to email amazon. It'll take a day for them to get back to you, but it will help determine what is going on.

Do you have a different book in your account that is priced at 35%? That might be showing up.
