Sidecar relay port issue

I've run into an issue with a digital sidecar lately. I seldom use relays but this year we have an LED on the back of our robot that tells our drivers when we're ready to shoot. We're controlling it with a spike relay. The issue is that the relay ports are completely unresponsive.

Our team uses java to program our robot, and I've tried every possible way to turn on a relay in java. But the only thing that changes the state of the relay is disabling/enabling the robot. The strange thing is that about half the green and red LEDs that indicate the state of the relay ports stay on when the robot is enabled. I've tried a different sidecar only to get the exact same light pattern. I've look all over Chief Delphi and no one else has this issue. I also look at the sidecar documentation and I don't think this is supposed to happen.

If you have any ideas on how to fix this problem please post.

Thanks
