DND: phone still vibrates even though my only exception is Alarm, no priority callers, etc.. HELP

[AC Question]

Hi,

I just got an update on my S5 and blocking mode was then changed to Do Not Disturb. Thing is, when I enable DND, I still get vibrating notifications from updates and texts, even though my only exception is my Alarm. I have no priority callers. Even if I mute my phone, it will still vibrate when someone contacts me or my phone updates something. Any help with this would be awesommmeeee.
