CCleaner Pro does not close after Opening

Do not know if this has been posted. Just started having problem with ccleaner not closing, and remaining in systray after closing. Have do a hard click Exit, to get it to close. Why does ccleaner stick around, like active monitoring etc. afraid to say free advertising? is there a new setting i missed to close after opening? Disable active monitoring has disappeared. Have to stop it from running at startup with paid uninstaller, just like I have to do with windows defender. is money that tight?

Turn off smart cleaning which is what monitoring was renamed.

that seems to have worked, guess I was supposed to guess that.
