Disabling/Enabling NAT rule under sheduler

I want to enable and disable NAT rule with sheduler. Why it works under terminal, bot does NOT work under sheduler? MT3.22.

/ip firewall nat set 3 disabled=no



/ip firewall nat set 3 disabled=yes

You have to use ‘find’ command, numbers are not supposed to be working.
