Airstair issue with GSX level 2 and PMDG 737NGX on P3d V3 while deboarding

Hello, I just installed GSX and I am facing a visual issue.
I landed on Aerosoft LIME an parked, requested deboarding and opened doors and fw airstairs.
Also opened luggage doors.
Everithing was fine untile people started deboarding, the rear people are ok, the front appear  directly on te ground near the nose weel, move fore about two feet and then stop, the continue the animation but does not reach the bus.
Did I did something wrong?
I am simulating Ryanair so no jetways and no forward airport stairs are in use.
Thank you for your help

The latest GSX includes an updated configuration for the 737 NGX with the embedded staircase, use the Reset button in the airplane configuration to be sure it's used, otherwise any customization you might have made will take the priority.
