As you can see in the screenshot is all ok. Loaded the map only with Easy Dev and DLCs. So the errors must be from a mod...

It's a normal wheat field, which is why it's strange that the function isn't working. It's autumn-sown wheat, if that matters.
I had an idea, and it worked. Since my problems were related to the vary basics of the game, I reinstalled it, and the anomaly disappeared. Sorry for the disturbance I made.
