I have two railings on my stair. One is Associative and one is static. After some struggle I have gotten the associative one to show in an acceptable fashion on both stories. On the static stair I have not found any way to have it not show below the break line. I have gone through every possible setting and none of them affect below the break line. But you can see the break line exists on the home floor. I have attached images of the stair and settings.
