CCleaner not cleaning on exit

First, I am running windows 10 with latest updates, as well as latest release of CCleaner Pro. Recently noticed that I am no longer being notified that CCleaner cleaned MS Edge upon exit, and I am getting new notifications now after exiting MS Outlook that CCleaner cleaned Internet Explorer (?).

I always received CCleaner notifications after exiting EDGE, and never before received notifications after exiting Outlook. Very strange.

I have made no changes to default settings and there is nothing in the settings options that would explain this behavior.

Any ideas? Other than this, my machine runs extremely well and fast.

Thanks. . .
