You beat me to it @DensestSnail693, I was just about to post the same screenshot LOL.
@Skycamry360 - note that the other Kingair entries on the list when you search for Kingair (those not shown as by “Textron Aviation”) are various liveries that will be installed. I doubt that you will need to remove these as well as the aircraft itself, but if the uninstall/re-install doesn’t work if you leave them, try uninstalling them as well and see if that helps.
There may also be an issue with the KATL area - do you have any mods etc, such as a custom airport for KATL?
