No idea how I got here, but for some reason I have GSX gates at KCLT (which I'm okay with in concept as the GSX gates are much better) but they do not align with the scenery very well.
That's precisely why you are always supposed to exclude jetways if you have an add-on.
I excluded KCLT in the Installer config page by adding it to the lists to disable jetway and airport services. After running MSFS and exiting the sim, KCLT no longer appeared in the lists in the config page.
First, you shouldn't have done anything, because anytime you perform a GSX update, it will automatically exclude all jetway for any 3rd party airport you have an add-on for. Of course, for this to work, the airport must be installed and linked to the Community. If you install the airport later, you can exclude it manually.
From your screenshot, the only thing I see is that KCLT is not in the Disabled list, so it doesn't seem you ever disable it so, considering you see the GSX jetways, the only possible explanation is the airport is still in the Enabled list, meaning you didn't excluded it.
So, either type the ICAO manually, and move it from the Enabled to the Disabled list, or just click the "Exclude 3rd party" button, which will automatically search again for airports to exclude.
