My planted maps look the same. I use JD 2630 into SMS. BUT, if I do a split planter the whole map is covered. No skips. I talked to SMS customer support and I did not get very far. They did not have a answer. I have just lived with it for several years. Has not bothered my harvest maps.      It can be handy. If you have a area you want to look at, you can count planter swaths to get there. It does work.
