All blocks in this if statement are identical. (error in running GUI)

Hi, I'm new in GUI and not familiar with the command. When I try to run my GUI It always show 'All blocks in this if statement are identical. Avoid identical blocks to prevent unexpected behavior.' Wh does it happen and how to solve it?

% Button pushed function: checkButton
        function checkButtonPushed(app, event)
            
            %for normal skin is chosen
            app.NormalSkinButton.Value = true;
            for  i = app.NormalSkinButton.Value
                
                %control statement for skin problem
                %the selected skin problem will display the specific solution
                %fix image with size of axes
                if app.AcneButton.Value == true
                    im = imread('skin.jpg','Border', 'tight');
                    imagesc(app.UIAxes,im);
                elseif app.DullnessButton.Value == true
                    im = imread('skin.jpg','Border', 'tight');
                    imagesc(app.UIAxes,im);
                else 
                    im = imread('skin.jpg','Border', 'tight');
                    imagesc(app.UIAxes,im);
                end
            end

Were does this message occur?

I do noit understand the purpose of your code also. Your code:

for  i = app.NormalSkinButton.Value
    
    %control statement for skin problem
    %the selected skin problem will display the specific solution
    %fix image with size of axes
    if app.AcneButton.Value == true
        im = imread('skin.jpg','Border', 'tight');
        imagesc(app.UIAxes,im);
    elseif app.DullnessButton.Value == true
        im = imread('skin.jpg','Border', 'tight');
        imagesc(app.UIAxes,im);
    else 
        im = imread('skin.jpg','Border', 'tight');
        imagesc(app.UIAxes,im);
    end
end

does exactly the same as:

im = imread('skin.jpg','Border', 'tight');
imagesc(app.UIAxes,im);

I assume the code analyser sees this simplification also and gives an advice.
