TOPIC: Cookies are not deleted if Decline button is clicked

There is still one thing I can not understand how it works.

I've activated block iframes option.
I have three cookies of Google Analytics key(name) _gid and key(name) _ga, _gat
If I click in Cookies options on "Decline" one of them or "Decline all",
I can still see those cookies in the Application > Storage > Cookies of my Chrome browser after page reloading,
should they be deleted ?
There only the value of cookiesck changes to yes or no if I click "Decline all" or "Accept all" but cookies _ga, _gat and _gid are still there.

Thank you!
