One problem at a time: first the couplers, then the Quick Drive destination markers.
I believe there is a limitation to creating trains using the Quick Drive custom train creating window: there is no asset selection/object set possible using the window. You also cannot set a load on the car or change its number.
Since the GP30 locomotive comes in a different collection from the couplers, the Kuju collection is probably not selected and enabled in your custom QD train.
Have you tried putting a Kuju car into your train?
Search the Kuju/RailSimulatorUS/RailVehicles/Freight folder for an easily distinguishable car that is not a repaint and add that to your train. That car should use the couplers from the Kuju/RailSimulatorUS and perhaps force the coupler onto the locomotive as well?
