Hi @152bobby,
As alexdon said you need to reset the app preferences. However, instead of doing it for all apps you can also do it for just the Sound Picker app. Go to Settings > Apps > All > Sound Picker > Clear defaults. The next time you try changing a ringtone or notification you will get several options to choose from again. 
Go to settings-apps-all, tap on 3 dots and reset app preferences. This will reset customizations for all apps but it's not difficult to set them all up again.
EDIT: Thanks @Christofer, that's a good answer and it should work, but there were cases where people couldn't find the app that was customized to open some files.
