Don't panic. I'm doing the Sweet Tomato Heel, which calls for 2/3 of the stitches to be used for the heel, and the other 1/3 for the instep. So if you start out with the sts evenly divided 50/50 between instep and sole, you have to rearrange them on the needles for this particular heel.
I've never done a Fleegle heel nor even read the directions. So if your instructions say nothing about dividing the sts differently, then you're fine. I didn't mean to alarm anyone.
There are so many heel constructions, and they all require different things.
