Some of the Map Layers in the Hunt folder shade the map or obscure features. If your map is blacked out or is shaded a certain color, most likely one of these layers is on.
Tap the Map Layers Button in the bottom-left hand corner to open the Map Layers Menu.
Map Layers are grouped into a series of folders. Tap the "Hunt" folder to open it.
Turn off any layers you have on by tapping them one-by-one to see how the map changes.
