Those decisions are made by the Wildlife Biologists based on deer populations.

I know some of the areas, 4a for one, are different and can be confusing. Unfortunately as you pointed out if you use your either sex tag in Willington your only other option outside the zone is a doe. If you would like to make your concerns known you can contact the Deer biologists at Franklin Woods Wildlife Management area. It may be something for them to consider next season.
