GSX surely recognizes SODE jetways, and there's nothing you have to do, other than being sure SODE has started when you call GSX.
However, it's not clear from your message, if the problem happens ONLY on 3rd party sceneries that use SODE jetway, or also with FSDT sceneries that use SODE, like KIAH, KMEM, KCLT and KSDF.
