Bittle X Knees and Arms go in the wrong direction when standing and walking

Hi! I have been setting up my pre assembled Bittle X, but I have issues with the Knee and Arm servos in the Joint Calibrator part. They go in the good position for the "Callibrate" and "Rest" poses, but if I try "Stand up" both the Arm and Knee servos look like they are going in the opposite position than what is expected on the image displayed.

Any advice? I attached an image of the "Stand Up" position so you can see what I mean.

Thanks!
