Silent mode

Why does Silent mode trigger a Notification Alert that Silent mode is on; which I cannot clear unless I turn off Silent mode?
Any fix for this?
I do not what any alerts for things working like they should, thank you in advance.

What Avast program and version number are you using ?

I’m still using Avast Free 21.5 (I’m hanging back on 21.6 and 21.7, recently released) and mine works as I expect, no alert/popups. If I open the UI myself, I see that there is a Notification that Silent Mode is ON. But I can close the UI without switching the Silent Mode off.
