See TRF post. You can select the motor name formatting in the motor selection panel to "common name" (e.g. 'B6') or "designation" (e.g. 'B6W'). However, in the flight configuration name, the common name is used by default (e.g. '[B6-6]'). It would be better to apply the select motor name formatting in the motor selection panel to the flight configuration, so '[B6W-6]'.
