Those extra jetways ( the bad-looking ones
) are not part of our scenery, they look more like default jetways.
This can be caused by another AFCAD in conflict. They usually come with addon AI traffic packages, like MyTraffic, etc. You can use the AFCAD utility to look for any airport for PHNL.
There must be only 2: the default one that in the default Scenery folder, and the one in the FSDT PHNL folder.
If you have more than 2, remove the extra.
