Mission planner do not recognizing RCMAP

Using Sbus with JR radio I had to RCMAP the channels to THR, Eleron, Elevator, ruder in RC1 to RC4 respectively.

While reversing channel 3 (elevator) it is shown in the RC calibration panel like the throttle is reversed.

It looks like Mission Planner did not consider the remapping.

Do I miss anything ?
