Galaxy S5 :: Background Data Disabled - Google Play Store Needs Background Data To Be Enabled

I have noticed an issue with the Galaxy S5 that apparently only occurs with the Verizon variant. I work for a place called Wireless Advocates, we are the cell phone kiosk inside of Costco. I'm asking about this because I've had three customers come in to ask about this background data issue.

I'm not sure what triggers this issue but when I try opening up google play I get the "Background Data Disabled : Google Play Store Needs background data to be Enabled" error. It then gives you the ability to either quit or enable the data. If you press enable it takes you to the account screen in settings.

When I go to Data usage the option to "restrict background data" is greyed out. You can't even select it and it isn't checkmarked either. Just to clarify, accessing the internet and other things on the phone work perfectly fine. It's just the use of Google Play that is having issues. I called Samsung customer care and they aren't aware of this issue at all. Also note that force stopping google play, play services, removing the google accounts and adding them back and rebooting the phone haven't solved it. After the reboot the phone will appear fine and then a box that says "Restricting background data".
