I have the same issue. When I upload a header photo 2000×500 it zooms into the top left corner of the photo. I tried to switch it from Fixed to Scroll but after I save as Scroll, when I view site it returns to the zoomed in photo. And then when I return to the Customizer the setting is back on Fixed again. No matter how many times I try to set it on Scroll it always returns to Fixed.
