Unable to get some Fields of a contact using Live Contacts API !!

When am doing a'GET' request i don't get the fields'Nickname','Website' and'Notes' in the response for any contact. Am getting the values of all other fields. I have set these fields also while creating the contact at Live but i still can't obtain the value of these fields. Is it possible to obtain these values ?

Also another problem is that when am deleting a contact and then adding a new one(using'DELETE' followed by a'POST"), sometimes it shows the'Nickname' which was added previously for the deleted one, in the new contacts'Nickname' , though i have not added any 'Nickname' for the new contact. Any suggestions as to why is this happening ?
