Help Obi Collision Detection

[meryemekinci]

I have objects with ObiCollider & Obi Rigidbody on them, and they are forced to move at some point. I need to limit their movement, and I also need them to be destroy after a while, in my case when they hit the collider at the top(You can see the colliders in the image below). But Unity's trigger methods seems not working in my case.
