Aperture broke my exported image!

[opus]

Anyone have any idea why this happened? I made some extensive adjustments and then exported, and got this "three panel" effect. Anyone have any idea why?



These are my adjustments:



This is what it should have looked like (this is a screenshot):



I've tried exporting multiple times and in multiple ways, but I still get the same thing.
AND, what's more, I've tried recreating the image from the original, duplicating the exact same settings/numbers, but I can't get the histogram to look the same, so the sky is washed out.
