From my understanding as a local, Disney is more complicated to work with than your average mall. At both Disney Springs and even at the newer Disney owned Flamingo Crossings, it has been difficult for some shops due to Disney's costs and rules. Expect it to cost more money than any other location and have more rules that may or may not make sense. This is why you don't see unique businesses unless they are owned by someone with a lot of money. Definitely not an easy place for mom and pop type shops.
