Vodafone Smart Ultra 6 contacts question

when I go to phone book I have options speed dial, recents and contacts. In contacts they are all duplicated, showing phone and SIM. I have gone into the contact app and in the settings 'contacts to display' have ticked Phone-only, unsynced. It shows only phone contacts in the app but going back to the phonebook still shows both phone and SIM.
How do I show only phone contacts in the phonebook??
