Why are you updating scenes after you make them? Just do this.
Make the layer Cab A the only visible layer. (Layer 0 always remains active, though). Then create a scene for Cab A. Next, turn off the Cab A layer and turn on Cab B layer. Create a new scene and name it Cab B. Make the Cab B layer invisible and make Cab C layer visible. Create another scene. Rinse and repeat for the rest of the layers. No need to do any updating at all.
