findContours Problems with CV_RETR_CCOMP & CV_RETR_FLOODFILL

The contours are wrong:

Mat arr(10,10,CV_8UC1,Scalar(0));
rectangle(arr,Point(2,0),Point(6,0),Scalar::all(1),-1);
cout << arr << endl;
vector<vector<Point>> contors;
findContours(arr,contors,CV_RETR_CCOMP,CV_CHAIN_APPROX_NONE);

for (size_t i=0;i < contors.size();i++)
cout << boundingRect(contors[i]) << endl;


Mat arr(10,10,CV_32SC1,Scalar(0));
rectangle(arr,Point(2,1),Point(6,1),Scalar::all(1),-1);
cout << arr << endl;
vector<vector<Point>> contors;
findContours(arr,contors,CV_RETR_CCOMP,CV_CHAIN_APPROX_NONE);

for (size_t i=0;i < contors.size();i++)
cout << boundingRect(contors[i]) << endl;


findContours Problems with CV_RETR_CCOMP & CV_RETR_FLOODFILL

The contours are wrong:

problem1: Mat arr(10,10,CV_8UC1,Scalar(0));
rectangle(arr,Point(2,0),Point(6,0),Scalar::all(1),-1);
cout << arr << endl;
vector<vector<Point>>     vector<vector<point>> contors;
findContours(arr,contors,CV_RETR_CCOMP,CV_CHAIN_APPROX_NONE);
findContours(arr,contors,CV_RETR_CCOMP,CV_CHAIN_APPROX_NONE);  for (size_t i=0;i < contors.size();i++)
cout << boundingRect(contors[i]) << endl;
Result1:  Problem2: Mat arr(10,10,CV_32SC1,Scalar(0));
rectangle(arr,Point(2,1),Point(6,1),Scalar::all(1),-1);
cout << arr << endl;
vector<vector<Point>> contors;
findContours(arr,contors,CV_RETR_CCOMP,CV_CHAIN_APPROX_NONE);

for (size_t i=0;i < contors.size();i++)
cout << boundingRect(contors[i]) << endl;
Result2:
