This is definitely weird. Are you using vanilla u-boot and no changes on top with the sama5d3_xplained?

Yes it should not include it. And if you write using sam-ba the nand header will be written by sam-ba, so your binary should not include it already. I also suggest you open up a support ticket on support.microchip.com as our FAE have a lot of experience to assist with such situations.
