Idle Quick scan - remove Cookies?

I have noticed that my Idle Quick Scans do not seem to remove Cookies even though I have the options in Computer Settings | Computer Scans | Tracking Cookies Scan set to Remove.  A manual Quick Scan or Full System Scan does remove Cookies.  Is this normal / correct?
