This is happening to me after install something in N9qtweak, for example I have mmm Richard added on my CONTACTS, normally if you or me send a message to richard on the messages view you see his name. But is not showing the name to me, when I receive the message I see his name on the notification on the lowpower screen but not on messages view, so is there something that not update the names there.. Because if I Do A Full Refresh It shows the names on messages but it continues happenning if another contact send me messages... Somebody can help??
maybe powerpack or busybox or fastern9 make this???

It's powerpack
Try reinstall it

are uuuu suuuuure??
