I pulled the Switcher apart and checked the wire hook-ups. Found all connections to be per drawing but reversed the wires for the lights and solved the problem. I don't know if the issue originated in the Bachmann decoder or the Switcher.
The decoder was a tight fit so if I had to do it again I would get a smaller/n-scale one.
