Nate Thanks a lot, setToSetupPose helped. setEmptyAnimation did not change anything.But I don't understand - why, if I changed the animation to move, did one of the effects of the old animation remain? I changed it here
 
private void HandleAnimationComplete(Spine.TrackEntry trackEntry)
    {
        if(trackEntry.Animation.Name != "move")
        {
            animator.skeleton.SetToSetupPose();
            Debug.Log("cleared: " +  trackEntry.Animation.Name);
            animator.AnimationState.SetAnimation(0, "move", true);
            _movement.MultiplySpeed(1);
            _usingSkill = false;
        }
        if(trackEntry.Animation.Name == "jamp")
        {
            gameObject.layer = 3;
        }
        
    }
