Question [Q] Do Not Disturb question

Just updated my HTC one to sense 5.5 and have my "Do not disturb" set with the exceptions list. I know the exceptions list will allow those contacts calls to come through but what about the text messages? I still get no sound notification when a member on my exceptions list sends me a text. Is this normal or did I miss the setting? I've been searching with no luck so far. Thanks!!
