[HELP] Notification Trigger intercepting HeadsUp Notification A13

So I'm triggering a task when a certain notification text from a certain app is received.

The trigger works fine and the task is working as intended.

The problem is that the notification itself gets "invisible" for Android: no headsup notification, not vibration. The notification is only shown in the drop down bar.

​

Am I missing some setting or is this a known Tasker "bug"?

​

Thanks in advance for your help and sorry if this has been asked before, but the wording is a bit hard to differentiate.
