Multiple iris sim problem in v1.14.3

,i meet the same problem when i try to run .sitl_multiple_run.sh dds can connect correctly,and three iris could be seen in gazebo also in terminal i run ros2 topic list i can see px4_instance namespace. But i found that i cannot control any of them through ros2 node. I echo their odometry and found their position in gazebo not match odometry(three iris out y=0 should be y=3 6 9 )i try to run listener trajectory_setpoint in qgc found that vehicle received my data through node but no response in gazebo. Make px4_sitl_default run perfectly .can you help me . appreciateļ¼
