Firewalld ICON disappeared on system tray

Just installed OS with latest nova build.Live user was displaying firewalld white ICON on systemtray
After installation for the first boot , firewalld ICON was not visible on system tray.Is it the way ISO has been built or just happening to my laptop?.
From programs, we can start firewalld
firewalldicon
application.But it would be convenient to see its status on system tray
