I noticed an odd problem on my iphone 6 after someone called me, and I added their number and name to my contacts. Or thought I did. When I search my contacts, they are not there. But when I go back and check my recent calls, the name I gave them when I added the contact is displayed, and when they call me that name will come up on the screen as well. But they can't be found in my actual contacts. I tried adding a couple of other numbers as a test, and the same problem occured. They are not making into my address book for some reason and I can't search for them by name. What's going on, and how do I fix this?
