I run the GSX control panel to disable default jetways form my sim. I undertand GSX is able to replace non-SODE jetways with SODE jetways in ZRH correct ? Upon accessing the customisation parking slots, I see they have all the /J except one that has /JS. The /JS is the sole that is visible and actually work on the scenery. When I try to edit the /J ones, all the entries are blocked (grey) and I can't edit anything ? I notice also that the Jetway name entry field has a number like a registry number, in grey so that I also can't edit it. Is that normal ?
