Unity 2D colliders not triggering,Unity 2D collider not triggering

I am currently making a 2D game in unity, and i am trying to insert a falling platform, whenever i stand on the platform, its supossed to go down, for this i used 2 box colliders, and only one of them isTrigger, but whenever i stand on the isTrigger collider, it works as a normal collider. Please help me.

also, i tried activating the falling platform with a press of a button, and it works perfectly, the real problem is with the colliders.
