Java OPENCV Template Matching gives wrong coordinates?

Question

so basically I am using Opencv Template Matching and it finds the correct match in the mainimage but the given coords of the match are wrong.

mainimage

subimage

result

As you can see in the third picture, the algorithm found the right match. Also i wrote a print x, y to see the coords of the match and this gives me the following coords: 330, 1006. The value of x is right but the value of y is not right? how is this possible?

Code of the template matching method:

public void FindImageInFOE() {
    System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    Mat source = null;
    Mat template = null;
    String filePath = "C:\\Users\\Gerrit\\Desktop\\";
    //Load image file
    source = Imgcodecs.imread(filePath + "jpgbeeld.jpg");
    template = Imgcodecs.imread(filePath + "jpghelpen.jpg");

    Mat outputImage = new Mat();
    int machMethod = Imgproc.TM_CCOEFF;
    //Template matching method
    Imgproc.matchTemplate(source, template, outputImage, machMethod);

    Core.MinMaxLocResult mmr = Core.minMaxLoc(outputImage);
    Point matchLoc = mmr.maxLoc;
    //Draw rectangle on result image
    Imgproc.rectangle(source, matchLoc, new Point(matchLoc.x + template.cols(),
            matchLoc.y + template.rows()), new Scalar(255, 255, 255));

    x = matchLoc.x;
    y = matchLoc.y;

    Imgcodecs.imwrite(filePath + "succes.png", source);
    System.out.println("Complated.");
}

The Y coordinate is correct, it's counted from the top of the screen.

Top left is (0,0), bottom right is (1920,1080) on fullHD
