I sideload another batch of 38 books the other day (using Calibre 'send to device'), and then realized about 9 or 10 of them were missing the cover art. Went back to Calibre and did the epub to epub conversion to fix the cover art issue mentioned in another thread.
Now for the funny thing: those books no longer show up at the top of the library when I sort by most recent. If I search for any of them, do a long press and review details, they have today's date on them. If I open any of of the books and go back to the library that book does show up first.
Tried a sort by author, then resort my most recent without any change. I even did a reboot to see if that refreshed something but still no change. For grins, I sideloaded the books again with Calibre and they still don't show up first in the library.
Calibre shows the reconverted books with today's date, and if I sort by date those books are on top.
So any ideas what gives in my poor little NC's confused library?
