Needs Refil Error CoursePlay only

[Helazak]

I have a John Deere P576 Air Hoe Drill with its C850 Air Cart being pulled by a Versatile 4WD 620.
I have a second one pulled by a Case IH Steiger Wheeled 620.

Both have the same error.

If I use base game helpers they will sow a field just fine. (As well as they can anyway.)
But when I use CoursePlay I am getting a "Needs to be refilled" message. But nothing needs to be refilled.

Used to work fine. Anybody having this issue?

Hello! your problem is in the courseplay setting - fertilization with a seeder

AAAAHHH GOT IT. I had originally used seed only because I wanted to use a different fertilizer but my fix was to include both seed and fert which solved the problem.
I see the Fert setting now. Thanks
