Yes, Security & maintenance and possibly Settings are the ones I would think you need to turn off.
Odd, it lets me toggle it off. Is it greyed out, or just won't toggle? If each app is greyed out, check that the main 'Get notifications from apps and other senders' is on. If you can't turn off individuals, can you turn off this 'master switch' for all notifications?
Or it could just be that with a restart thought to be needed you are temporarily disable from changing these settings...
