I lost my 'add custom label' on my iPhone 6+
I have an iPhone 6+ and lost the availabilty to add custom labels to my contacts. I have the @me as my default contact under the mail, calendars and contacts within settings, Sometimes, the "add custom label" will show up but when I try to use it, it won't go into the contact and then I'll lose the the "add custom label" again. ack ack ack --- help please. I also had to reset my ring tones again and I'm not sure what else has changed - it's a mess!
