Controlled Pipe Junction is bugged

[Paineframe]

When the Controlled Pipe Junction component from the Mechanic vendor is switched On, then it will always send items to the right, no matter how it's oriented. I've tested every orientation except "vertical with 'On' outlet facing down", and no matter which direction the outlet is pointing or whether it has a pipe attached to it, the shit I send through the chute always flies to the right when it hits that pipe segment, even if it means magically flying through the wall of the pipe. And yes, I had the pipe properly welded to the underfloor and toggled on with a component.
