Help Group contacts screwed up

[rogone]

After I did the update before last (not the one that became available this week) I noticed that my contacts within groups were no longer in alphabetical order like they are when I look at all my contacts together. Prior to the update the group contacts were in alphabetical order. I have been in a Sprint store and asked a salesperson in Best Buy and nobody seems to know how to fix the problem. Anybody have any ideas?
