I'm having an odd problem all of a sudden and wanted to know if anyone else had it happen to them. Since I have an SD card, I thought I may as well use it and have been moving books I've read over to it. Yesterday went just fine. Then, I had the bright idea to also move over some of the backlog of waiting to be read books so that my home page wasn't so long. Still went fine. THEN..... I purchased two new books. I moved them to SD memory. They show up on the SD card AND still show on the home page which should only show Kindle memory. I have tried deleting them (love the new easy way to delete) and reload straight from Amazon to the SD card. There they are on my home page Kindle memory! Any tips for me? Thanks.
