I am a UK resident and all of my print books and e-books are available on Amazon.com and UK. On your project page click on manage. Then tick the Amazon Kindle box. If you have already done this, I would suggest contacting an admin.
I checked your listings, one appears to be on Amazon, the other is not selected for Amazon. You'll want to click the "Manage" button and check the Amazon box to get the files sent to Amazon for approval.
