Lumia 1520 :: Notifications Sounds List In Settings

I performed a hard reset on my 1520 due to the camera freezing up on me after I pressed the shutter button. However, a new issue has arrived. Once I set up my phone again, using my most recent backup, I signed into all of my apps as usual, and then I found myself in Settings setting up my notifications sounds, banners, etc. But, the list was very short. The only apps in the list were the initial apps on the phone: messaging, phone, the email accounts, etc. Before I performed my hard reset, the notifications list included 6tag, Kik, and every other app that had notification abilities. Now, they are gone.
