Plane sink rate at autolanding

I’m setting auto-landing parameters using mission planner on my V-tail plane. I’m using pixhawk 2.
My confusion is that the LAND_FLARE_ALT(set to 2m) and LAND_FLARE_SEC(set to 3m) sets the descend rate of the plane once it’s at flare stage, which calculates to 0.67m/s. However, the TECS_LAND_SINK(set to 0.25m/s) parameter also sets the sink rate of plane, so that it has a smooth touchdown.
so what parameter will the plane follow if both values are different?
