No Command on ZW A Terminal???

Hi everyone. I'm new at all this and just getting into CC. I've had a conventional set-up for the last 5 years, but just got a new Command Control GP-30 and me and my 3 y/o Son love it and the Odyssey system is just awesome. I have a question though concerning my ZW not working properly, well, yes and no.

A B C D terminals on the new ZW. If I use the A terminals, Powerhouse to A plug and connect track power to A, and outer rail to U common above A terminal, and the command base to the same U, put engine on track, then power up track, I get nothing. But, if I stay on A and just pull the command base wire off, I can run my engine conventional.

But then, if I keep powerhouse on A and put the jumper plug in below the B terminal and connect track power to B and outer rail to U common above B terminal and command base to same U, everything works perfectly. Any thoughts on what's going on here? Had the ZW and both bricks tested at service center and said are fine.
