CharacterMovement AddForce Replication stutter

I can’t understand why AddForce causes character stutter on low velocity while it works just fine with the input vector
Also, adding force on server and client causes behavior very different from singleplayer mode(need more force in single to leave the ground)

I have: default Character and Volume that adds vertical force

And this is what happens on client:

PS. I’ve modified air control and in video you can see that slow horizontal move is fine while vertical acceleration stutters because client tries to fall while server accelerates up
