On a Kindle Fire (not HD/HDX) do you see books when the CLOUD is displayed that you deleted via Amazon Account's Manage Content and Devices? This has been reported back in 2011 but I found no simple answer to correct it and get rid of the erroneous books. I found a KINDLE app that manages them via local data, i.e., on the device itself, that was NOT handling some books, usually those borrowed via a public library for free, an although they do disappear from a Fire HDX, they remained on my older Fire! Below is the solution to make them disappear and sync only with those you left on the cloud.
The SOLUTION: On the Fire, Amazon has an application called "Content Management Services". So,
1. Swipe down from top
2. Tap MORE
3. Tap APPLICATIONS
4. Tap INSTALLED APPLICATIONS
5. Scroll down until you find the KINDLE app CONTENT MANAGEMENT SERVICES and then tap it
6. Tap CLEAR DATA
7. Back on out ... you're done and the erroneous cloud data should now be gone for the books that still appeared but were previously deleted from your Amazon Account via it's Mange Content and Devices feature
I hope gone forever. We'll see if they reappear. This is Day 1
