D1 mini pro with Eventor problem

Hi guys
need your help with my Wemos D1 mini Pro using eventor.
i used eventor to turn On D5 pin at 8PM and Turn Off pin D5 at 815PM.
the problem that it’ll turn this pin on but doesnt turn it off.
if i use the same pin D5 but with the switch icon , it does turn it on and off
i have tried it on D6 too but same problem
Many thanks
