Apps not quitting
Monterey 12.2.1
I open the Calendar app, and close the app with the red dot, but it does not close the app, even though the app does not have a dot below it in the dock. When I go to the Apple in the top left corner and choose Force Quit, it is listed there as an app running (even though it does not have a black dot below it).
This same behavior happens with the Preview app as well. Why are they seemingly closed (with not dot underneath) yet they can still be found in the Force Quit list as if they are hidden, running in the background. Is this a bug? Happens on all macs I own - Mac mini M1, Mac mini, Macbook Air, MacBook Pro - anything running Monterey or previous major version.
