iMessage Contact Not in Contacts List

Hi All,

I have a contact that I saved from a group chat in iMessage. The name displays fine in iMessage, but doesn't exist in my contacts list. I've tried importing from SIM to see if it only lived there (not sure if that was a possible issue) to no avail. That's one issue; the other is that I don't have the option to delete when I go into the contact's info [through the group chat].

Has anybody had this issue?
