Scheduler - Port Forwarding

For security purposes I only want to forward Port 21 to my FTP Server during limited hours on certain days.

I have no problems getting the server to work on  always, but when I pull down on the Always it says you need to go to the Scheduler under advanced options.

I have done that and setup a schedule several times, named it and picked the days and times applicable and saved it.  I then go back to port forwarding and the only option is still only Always.   I then go back to the scheduler and there is nothing there.

Has anybody been able to get the scheduler to work on their Actiontec router for anything and more importantly for port forwarding?   (latest model and the firmware is up to date) 

Thanks.
