As explained on the manual ( Page 4, "Trial Limitations" ) regardless if you bought GSX L2 or not, SODE jetways will still be added, but they will work only in Trial airports so, it's entirely normal you will see them. If you are outside a Trial airport or an FSDT airport, a message will say they won't move when you will try to use them.
Fact you see SODE jetways at a FlyTampa scenery, it's because you have a scenery in conflict, one that comes with default jetways, so they have been replaced. The most common source of conflicting scenery are AFCAD files that came with AI Traffic products, which you must remove if you have an add-on scenery for the same airport.
