It looks like there's a problem with reading the AFCAD file. Other justsim scenery are working fine, and Sode is up and running
From your screenshot, it doesn't seem GSX had any problems reading the AFCAD, which seems the right one. And, if the scenery has SODE jetways, GSX will NOT read them from the AFCAD, but it will ask SODE for their list, since SODE jetways are not in the AFCAD in the first place, but they are added by the scenery developer using a SODE XML file.
The problem is not GSX but, instead, a problem with parkings not correctly set in the scenery, which is now something that current SODE version checks for, as explained here:
