I have a Clip Sport running 1.38 and a 64gb SD card. I moved a bunch of audiobooks into the /audiobooks folder but, for some reason, a number of books are visible in Folder/External but not listed in Card/Audiobooks. They’re not under unknown, either. I tried updating the properties, making sure the genre was “audiobooks” as well as deleting and then re-adding the content (disconnecting between delete and re-add to force an update).
I copied one of the missing books to the internal memory and it showed up just fine. Any idea what’s going on? How can I fix it?
