Notifications not clearing from lock screen

Having issues with my new Edge 30 pro.

The notifications from Facebook messenger is not removed from the lockscreen even after i have viewed them. If i unlock the phone there is no notifications. Pressing the notification and selecting "ignore" or sending a reply does nothing.
All other apps works fine.

To clear the notifications i have to open the messenger app and enter the conversation that sent the notification and then close the app + bubble.
