Pixhawk 6X config tab

hello,
I have installed Mission Planner Fixed Wing Firmware but in Confing tab I can see QP Extended Tuning.
Can anyone Explane why I treid reinstaling everything and rewriting Firmware but it is the same.
I need Extended Tuninig tab for controlling WP speed and also chaging speed during the mission.
I unlocked from full param list Q_Enable (1)
will it be okay to use it like that ?
