Notifications can no longer be changed

Just today something has disabled the ability to change notifications on every app. You go to each apps settings and then notifications and default is set and you click that and the sound choices are all blank with Apply at the bottom.

Re: Notifications can no longer be changed

Does this persist after a reboot? How about after wiping the cache partition? https://support.t-mobile.com/docs/DOC-20857. Or in Safe Mode? https://support.t-mobile.com/docs/DOC-20834
