PhysX gravity makes body jumpy

I have a physic body with some mass and gravity enabled. At evry Tick i apply some force to this body, not too much to overcome gravity, but not very low. And in the result I have not a body standing on a plane, but a body little bit jumping at random time. Why is that? Is it possible to fix this without using custom gravity?

I am adding force with AddForce to BodyComponent in one of my actor’s components.

Figured out this was caused by having

AddTickPrerequisiteComponent(MyComponent);

in PreInitializeComponents() function. Which is kinda strange.
