W1 Call History and Phonebook

If I ever go to check the Call History or Phonebook they are blank. If I press synchronise they will go and re-sync the data.  But if the phone sleeps the screen and then I wake it and go back to the Call History or Phonebook, they are empty again!
What use is that?
Why doesn’t it KEEP whatever it has indefinitely, and just re-sync IF you ask it to.
Or why doesn’t it just even push Call History onto the W1 anyway? It is a history so of course you want it there to LOOK at always.
And the phonebook… well, that is much the same… you WANT it there always!

Is this a bug? Can it be fixed to work properly?
