How to generate proper labelled image from MATLAB (Image Labeler) for image segmentation

Question

I get black image whenever exporting labels to file in the Image Labeler App in MATLAB R2019a

Here is what i do:

Export Labels > To File

Also, I know that PNG file's image value is composed as 0 1 2 and this is the reason image apperas black.

I tried this piece of code and I get the result with distingished but the dimensions of the image are changed.

    figure;
    [i, m] = imread('PixelLabelData/Label_1.png');
    imshow(i,m);

I need is Labelled png image with proper dimensions. How can I do this ?
