GUI Elements Changing Position on Subsequent Executions

I have a GUI that contains three buttons and two plot axes. When I run it the first time, the positions of the elements is off a bit, with certain elements are off-center - horizontally or vertically (see below).

If I close this window and run the code again, everything is as it should be:

Here is the code that generates all of the UI elements:

    % Create the app window
    app = figure(...
        'Position', [0, 0, 750, 875],...
        'MenuBar', 'none',...
        'ToolBar', 'none',...
        'Resize', 'Off',...
        'NumberTitle', 'Off',...
        'Name', 'CBT Field Curvature'...
    );

    movegui('center');

    % Plot Data
    axesH = axes(...
        'Units', 'Pixels',...
        'Position', [25, 425, 700, 375]...
    );

    set(gca,'xtick',[])
  set(gca,'ytick',[])
    set(gca,'XColor','none')
    set(gca,'YColor','none')

    % Plot Data
    axesV = axes(...
        'Units', 'Pixels',...
        'Position', [25, 25, 700, 375]...
    );

    % Choose Images File Button
    uicontrol(...
        'Style', 'pushbutton',...
        'Position', [25, 825, 100, 25],...
        'String', 'Choose Images',...
        'Callback', @chooseImages_Callback...
    );

    % Choose Positions File Button
    uicontrol(...
        'Style', 'pushbutton',...
        'Position', [150, 825, 100, 25],...
        'String', 'Choose Positions',...
        'Callback', @choosePositions_Callback...
    );

    % Save Button
    uicontrol(...
        'Style', 'pushbutton',...
        'Position', [275, 825, 100, 25],...
        'String', 'Save',...
        'Callback', @saveButton_Callback...
    );  end

Were you able to fiind the solution? I need help with this

Unfortunately not. I think I just lived with it before eventually switching all of my app development to Python.

The problem is likely within the callback functions so we can't diagnose the problem without seeing where the problem is likely having.
