What collision shapes are on the marble and the pipes?
Regardless of the shapes - are you maybe dropping the marbles straight at the pipe? If so, it may bounce exactly right up if you don’t provide any force to either side. Try offsetting the marbles position so that it hits the corner, it should then bounce to the side too.
