Strange physics simulation. Snap/dislocate/shift/parent

I made hangings some cloth, tried simulate physics but one side keep snapping to root bone.

If i simulate ONLY one side, its normal…

Simulate both sides occur snapping

If i simulate even last bone with right side, this bone will also snaps to the root bone

For my capsules, settings are default. Before i didn’t have root bone, just two chains, and it snapped to origin place.

Also, removed all constraints snaps the same way… I added more chain bones and they still snaps immediately to root bone except first one. Pressed all possible buttons, played with a bunch of fields. Nothing!

I’m new to unreal, may it be impossible to work with two+ chain armatures?

Ok, idk what is the problem is but i tried using addon for blender called “Send to Unreal” from epic games github. And this fix the problem, your welcome.
