Collision problem - very small stair is blocking player?

Please help, I am in test phase of my building, and when I want to walk through door frame - little red stair is blocking player!

All collision is set to complex.

If I move a blue concrete litle up, so I dont have that red stair - then I have not this problem.

Why is this small stair blocking player?

maybe the issue is in the doorway collision?

No,its not.

And sometimes on some stairs or small objects I have this problem - my character cant walk over it.

Where in options is settings that tells to character capsule - which object can walk, which cant?

There is a “can step up” option but that is within each individual object (the objects you want to walk on of course)

That option “can step up” is tuner on at every object.

So for stairs, I changed this options “Walkable slope” and now I can walk over my custom stairs.

But that bug with small stair in first picture on topic - is still here, and I cant resolve it.

I tried to increase this option “walkable slope” at every object, but dont work for my problem.
