Well, it sounds like it has nothing to do with being registered or not, and everything to do with using the "Recent" view.
I have had something like this happen to me before. The lesson I learned was, do NOT sideload books from calibre if the book is already downloaded to the Kindle!
Delete it first -- THEN sideload it.
What you end up with is two copies of the same book, and the Kindle cannot tell which one is the right one, making it very confused.
The biggest issue (there may be others, but this is what I first noticed) is that it completely screws up the Kindle's attempts to keep track of collections.
Unless you reconverted them, they still have the same exth 113 (mobi-asin) field, which is what the Kindle uses to
uniquely identify a book.
Similar confusion can happen in the EPUB world, I believe, if two books have the same UUID.
