Default chunks loading in superflat world type

So i create a new superflat world names Overpopulated village. Wonder if you can guess what i was gona do. Anyway.. So it loaded and i see tons of default chunks. They didnt stop, so I guess there were infinite. Next to the outside ones were regular superflat world chunks. This will probably be very annoying if you dont fix it. Sure i saw the duplicate but this is diffrent but ok i did have a world with this name already but it was superflat.
