Why is the approach procedure not sent with the flightplan to the Garmin D2 Mach 1 Pro?

Hello, I have the problem that the approach prodedure waypoints are missing when sending a flightplan from the Garmin Pilot App to the Garmin D2 Mach 1 Pro. I think it would be very handy to have a feedback from my watch when I apporach these waypoints. For depature and arrival procedures it is working and sent to the watch. Further tipps would be very appriciated.

Thank you and best regards!
