42131 - D11 Testing Operations are Backwards

[Yova]

Hello! I am having issues with my 42131 D11 build. I have gotten to the testing portion of the build, and when I perform the tests some of the operations are backwards.

For example, option 1 and 2 are backwards. So when I start test 1, the operation for 2 happens. Same thing with operation 3 and 6. Operations 4 and 5 work fine.

I've put in a help topic with Lego a couple weeks ago, but have not gotten any response. Below is a google drive link with the current status of the build with photos and a video.

Thanks!

I was unable to view the pictures or movies  and don't have that model but what happens if you swap the motor connectors 1 & 2 and 3 & 6 on the control box(es) does the issue resolve itself.

It won't even let me run the build. The app tells me the motors are connected incorrectly and won't let me perform any functions.

From what I can see you made a mistake at instruction step 117 and put the limiter for the gear selector 180° turned to what it should be.

Now that I know where to look I can confirm that the provided photos show the mentioned phase shift with respect to my build.
