Remove Messages Alert in Control center?

Excellent question, how to remove these alerts?! 

FW has been rebooted several times, upgraded and all steps where taken.. still the alert message.

I am now so used to the alerts that I do not notice new ones immediately. So you achieve exactly the opposite!

By me, add a minimum age, after the expiration I can delete them, the main thing is that I can delete them or do we have at some time 30 and more messages?
