to string and back results in different json

[howudodat]

class child {
public:
	child() {}
	nlohmann::json toJSON() {
		nlohmann::json j;
		j["Altitude"] = 100;
		j["Region"] = "Test Region";
		return j;
	}
};

	child c;
	nlohmann::json jc = c.toJSON();
	string s = jc.dump();
	nlohmann::json jc2(s);
	cout << jc.dump() << endl << jc2.dump() << endl;

Produces the following:

{"Altitude":100,"Region":"Test Region"}
"{\"Altitude\":100,\"Region\":\"Test Region\"}"

The parsed string results in a non json object

Also doing this:
string s2 = jc2["Region"];
Results in an exception

terminate called after throwing an instance of 'nlohmann::detail::type_error'
  what():  [json.exception.type_error.305] cannot use operator[] with a string argument with string

oops, I see that simply constructing a json object with a string crates a string json object and doesn't actually parse the json

	string s = "Some json";
	json j1(s);				<<<<< Creates a json object of string 
	json j1 = json::parse(s);		<<<<< Parses the json
