MAV_CMD_NAV_LOITER_TURNS rejected by QGC

QGroundControl

QGC is throwing an error ‘Command not supported … Command: Loiter (turns)’ when uploading the mission for a vehicle with MAV_TYPE = MAV_TYPE_VTOL_TILTROTOR. This vehicle takes off in vtol and then transitions to fixed wing. Any ideas?

PX4: 1.14
QGC: 4.4.3
