DCC EZ Command #6 Crossover Shorting

[devillin]

I have two of these crossover sections on my layout, and I am able to control them fine. The problem I am having is that if I leave them closed, an engine coming on the second track will short out crossing over the connecting rail. When I remember to open the switch, I don't have this problem. Is there something wrong with my crossovers, or am I doing something wrong other than leaving the switch closed?

On a related note, I also have one of the WYE switches where if I leave the rail open or closed, one side of the switch never has power. I thought it might be because the black wire underneath was disconnected, so I plugged it in, but that doesn't make a difference.
