challenger 650 Default ATC Issues

[WamblingGnat844]

I don't fly on VATSIM that often, but I'd still like ATC. However, the default X-Plane 11 ATC has an annoying problem when it comes to the Challenger 650: When I'm in cruise, ATC will call up and ask me to "descend and maintain" my cruise altitude. The problem is that, obviously, I'm already at my cruising altitude, and the autopilot is maintaining the altitude perfectly.

Are you sure the cruising altitude on the X-Plane flight plan is the same as the 650?
