Contact showing? A little help, Please.

Ok guys, I've been searching and searching for an answer, but can't find anything. I'm on a 6.5 rom and my contacts aren't showing when they call, just a number. I know this has been discussed, but I still haven't found the answer. I remember reading a thread one time on using adv config or diamond tweak to not use sim card. That didn't do anything for me. I used Sprite to backup my contacts. What gives? Can someone Please point me in the right direction. Thanks.
