You need to reboot the system to see it. Does that work for you?
Yes, rebooting does make it appear.
Weirdly enough, enabling session restore "When session was manually saved" and restarting, appears to break the "Log Out" functionality. Basically, click on "Log Out" and nothing happens. Switching session restore to "Last logout" and restarting makes "Log Out" work again ...
