UE4 Cloth Simulation does not see collisions

Unfortunatly I dont understand what I should do with the information you provided me with.

I have Physics Asset assigned to the cloth:

I made shapes in this Physics Asset:

Cloth gives 0 collides about these shapes. Cloth does not collide at all.
This is what every guider on YT did and it works in his project, but not in mine.
Why?

I use UE4-26. Maybe I have something disabled?
