I'm using Calibre Companion (full version) on a Fire 10. The last several books that I've synced over from Calibre Windows don't seem to work right. The bookmarks are not saved. If I bookmark where I stopped reading, then close/reopen the book from CC, it just starts from the beginning of the book again.

Probably related: The affected books also do not show up in the Fire 10's native book browser. Older books though -- that were synced previously -- do still show up, and the bookmarks do still work in those books.

It's interesting, that I've always converted to .mobi for books to go on my Fire (and on my previous Kindle Fire HD 7). With this last batch of books though, I thought I'd try .AZW3. When I realized that the bookmarks weren't working, I deleted the AZW3 files and converted my books to mobi. But those are not working either... Did I break my CC by trying to put AZW3 files on it ???

I checked the various CC settings and searched the help docs. No luck. I have plenty of unused memory, so no problem there.

Thoughts?
