Overlap is on the right side. Of tractor => where has the Antenna than be set
If your antenna is too far left, you will have a right overlap. So yes.
Is the antenna really offset? If not, might try tool offset. It is a bit less confusing.
Overlap on the right side means the antenna has a left offset.
Another way of thing about it, if you have right overlap then your tractor has right offset which is the same as left antenna offset. The offset is half of the error but make sure you don’t get confused by comparing old offset passes to new offset passes.
I think the same applies to the implement offset.
And if you are trying to force an offset by moving the antenna only in the settings, there are all sorts of problems.
pivotAxlePos.easting = pn.fix.easting - (Math.Sin(fixHeading) * vehicle.antennaPivot);
pivotAxlePos.northing = pn.fix.northing - (Math.Cos(fixHeading) * vehicle.antennaPivot);
Note that it is minus.
