Welcome to the community, @HowDoILandThisThing!
Airports are updated by the Infinite Flight Airport Editing Team, a group of volunteers who choose airports and bring them up to as high a quality as they can. It looks like KSMF might have been updated, but the gates don’t reflect an A330.
To keep things organized, this thread was made to centralize all of these sorts of issues. I’d recommend positing it there, where the IFAET will see it.
You’re new, so don’t feel any pressure, but I’ve linked the IFAET’s thread below if you’re interested in learning more.
