The standard SODE jetway FSDT included is connecting to the AI aircraft
GSX Level 2 jetways do not connect to AI ( yet ) so, if you see a SODE jetway that connects to an AI, it's not coming from our scenery but, likely, from another scenery for the same area the use SODE XML jetways, which you removed without removing its own SODE XML file from the SODE folders:
C:\ProgramData\12bPilot\SODE\xml
or
C:\ProgramData\12bPilot\SODE\sdx
