Farm Designer - UTM position - Zero Y position changed automatically

In my farmbot designer, the UTM is moving in the wrong direction. Instead of going inside, it goes outside the farm as per the attached image.

Please advice on a solution.

I found out the issue was that the Zero Y position was wrong.

Any idea what causes the FarmBot to automatically the Zero Y position?

Your encoders are enabled right?
Farmbot usually does not zero any axis automatically, only if you would run a sequence that contains “Find home”.

Yes, I am using the encoders. I did not use the “find home” option either.
