Default NFC not working

My mother in law just upgraded from a flip phone to a moto x and we were trying to show the android beam ability to pass pictures from her phone to our HTC ones. However, when I touch the phones together in the appropriate spots, the notification sound happens but the picture on her phone doesn't get smaller and give the option to tap to send. However, I can send her a picture the same way with no troubles at all so I know everything is turned on correctly. I can't really play with the touchless control on hers b/c she won't use it so if it's something in there, I've missed it. Can someone please give me a hand with this? Any help is much appreciated.
