There's a bug in mission from 1.6.3 test

Recently, I use the 1.6.3 firmeware to test the mission functions, and find a bug in mission when I used MISSION_SET_CURRENT function.
At first, I set a series of mission waypoint and use mission to auto takeoff. When the vehicle is flying in mission mode, I switched the mode to position, and use Mission_Set_Current command from qground, and the data ‘local_position_setpoint’ in mc_position_control become abnormal
The logs is as follows:
