As for the boxes un checking themselves, in my experience it is only the three that come after stormie, and that though they appear un checked, if you checked them they are still checked and will still receive the notification.

This error message appears to only happen because you double checked the boxes which looked un checked, and it's counting that as sending two requests to the same person (which can't happen). At least, that is what I theorize.
