Problems with sending commands from QGC to blurrov2

I am trying to use my Bluerov2 but the commands are not properly sent from joystick to rov. Whenever the rov is armed, the bot performs a yaw. When Forward and roll commands are given, again yaw takes place.

Hello,

What mode is the ROV in? Does this happen in MANUAL mode?
Make sure you have completed the step “Configuring motor directions” in our software setup instructions.
