S4 Car Bluetooth Contacts

[sheppy1]

Hi Guys,

So I've connected my S4 to my car and the car syncs the address book so that I can see the phones address book on the cars screen. Now this works fine but for some reason some of the contacts appear backwards so Surname, Forename. But some appear as Forename, Surname (The way I want them all to display). Does anyone know why some are displaying the wrong way around and how to make them all "Forename, Surname"?

Thanks
