Hi,
I have a Nook Glowlight Plus, and use Calibre to load my books onto my Nook and manage my library. Both Calibre and Android File Transfer say I have certain books saved onto my device, but I can't see them in my library on my Nook (not even when I search for them).

I have tried rebooting, and also completely shutting down, to no avail. Have also tried deleting the books via Calibre and reloading them but still not appearing. The weirdest thing is that I have already read one of the books on my Nook, so there is no problem with the file. Have also checked opening the books on my computer with Calibre and the work fine there.

Calibre says I have 75 books on my device, but only 66 are visible on my Nook.

All help gratefully received.
Thanks
