My HTC M8 makes a notification noise but there is no message

The notification sound occurs but there is nothing to show I have either received a text or missed a phone call, why? and what can I do to cure this problem.

Welcome.
Go into Settings and then Sounds and check over the list to make sure all is set to your liking.
