The PNG file's image value is composed as 0 1 2 and you cannot distinguish the image looks like the result from following command.

image = imread('XXX.png'); imshow(image) % Looks like a black image

To see labeled image, please use the following commands.

figure; image = imread('XXX.png'); imagesc(image); colorbar

OR

figure; [i, m] = imread('XXX.png'); imshow(i,m)

OR

figure; image = imread('XXX.png'); I = imadjust(image); imshow(I);

For your reference, here is a manual how to use the saved file through the exporting functionality as below.
