well, the pattern instructions arent bery clear so maybe what happened is that instead of putting the earflaps on right side out, you put them on inside out and now you're forced to purl instead of knit. if you're too frustrated with purling the whole hat (I would be), you can try frogging it back, flipping the earflaps over, and attaching the earflaps the other way.
I know you said that you thought they were correct, but that's the only that I can think that they would now be inside out.
