I have a set of powered A and dummy A units that were a custom run from @MrMuffin'sTrains. I run them as MU as TR27. All the lights work except for the green marker direction lights, the number boards, the inside cab lights, the mars lights, ALL. I am using the Legacy remote but I can't seem to find where to turn those on / off. I should be clear they light in red when the unit is going in reverse, so I know they are not dead. I have reset the engine. I have also run them as non-MU same results. What am I doing wrong??
