OK problem solved.
I used Calibre and removed the "I'm reading" tag in collections leaving it blank which reset all the preloaded books to unread and now they are hiding when I display "My books".
Now I just have to sort through all my books to mark the ones I have read and then I might actually get to read something to see how good the upgrade is...
So taming when do you find time to read? You are always solving everyone's problems?
