Ubitx transmission on USB instead on LSB

Biju Apkrcl
 

In my ubitx v4.3, i uploaded the KD8CEC 1.08 version to a new arduino and inserted. Calibration kept at 22 and bfo set on 11.997.975.
Reception is good , on exact frequency but transmission goes on USB on 40m.. which I set the mode LSB.
What to do??

Thanks in advance.
