My contact is only showing the first name!

I'm having a little problem, added a contact onto my phone as just a first name and later added this contact onto facebook, ive linked the two contacts and the facebook display picture is showing in my sms conversation, but only the first name is shown, whereas all my other contacts have both of their names, I'm not sure what the problem is, any help would be appreciated.

Perhaps you should read your post again and then clarify. You said in the post that you added the contact with just the first name. At least that's the way I read it.
