Hi Thank you.
I thought that because was a compatible aircraft was already pre-set. Nevermind, I did as you said and certainly there were wrongly configured. I just set them up exactly as per the manual page 48, but still not working.
When tested it boarding, the crew started climbing up from the first step, correct, reach the aircraft level, turned round step down and walked over the ground as it was the plane aisle. The picture attached shows how the crew is starting to step down (I confirm, this is a boarding service)and you can see two crew already "inside" the plane...
