iPhone 5 can't change email alert sound

Longtime iPhone user here. Got my wife a 5 for Christmas. She wants to change the email alert but no matter what we do it won't change. That is the only issue we have. I have a 4s and tried it (Sounds > Email) and it worked like a champ. We do the same thing on hers and it won't change. When she first set it up instead of setting up as new she did a restore from backup (she had a 4). Could that be the cause and should we do a 'restore as new'? She'd rather not go through that but I can't think of anything else. Other than this glitch it looks and works excellent.

Any ideas? Thanks in advance!!

Edit: She also tried changing her ringtone. Both it and email seem to be stuck on "Marimba". We already tried a reset and also turned off and back on - no dice.
