random contacts show up phone number instead of name on lock screen

[Z06_Mir]

No idea why but a couple of contacts names don't show up just their phone number on my lock screen hen I get a message. Once I unlock the phone (no password) I can see their names fine. Only does it with a couple contacts the rest are fine.

Are all of your contacts from the same source? In terms of Google account contacts or backup assistant or some other contact list.

I thought maybe it was an fb contact problem so I added the contact from scratch and linked them. No change. So far it's just the 1 contact.
