Removing standard jetways?

I’m creating an airport for MFS and as you can see from the image, the stock jetways are still there.
i can’t seem to find a way to remove them, i tried using the polygon with the exclusion and it excludes everything but the jetways.
Any ideas?
Thank you!

“To exclude a default jetway you need to create a new airport with the ICAO code of the airport you are working on.And then in the properties section of the airport where it says “to delete” .Select delete jetways.This will delete the jetways but keep everything else from the airport”. I copied it from the internet I hope It works How to Exclude and Remove default Jetway from MSFS | FSDeveloper
