I fail to see what is complex about your case Jane - I come across situations like yours all the time when I am acting as Trustee in bankruptcy. The facts are thus:-
1 You have an unsecured shortfall in your property to Picture.
2 Upon the making of a bankruptcy order Picture will have to value their security in your property, simply crystallising their position and confirming the level of their unsecured claim WITHIN THE BANKRUPTCY.
3 As a result of the bankruptcy you will be discharged of all unsecured debts INCLUDING PICTURE.
Why the CAB are having to take advice on this point beggars belief, and they are causing you more stress and worry by suggesting that the bankruptcy be delayed for no reason.
