App Designer UIAxes is blank regardless of what I do

If I simply start a new App Designer project and drag the option "Axes (2D)" to the main canvas, I get the component app.UIAxes, but it is completely blank. While I'm dragging it, I can see the default labels, title, ticks, and so on, but whenever I drop it it just becomes blank. I also can't seem to make it work via code either, as shown below (image attached as well). Any ideas on why this is happening and a possible workaround?

        function EditFieldValueChanged(app, event)
            value = app.EditField.Value;
            x=linspace(0,10);
            y=value*x;
            plot(app.UIAxes,x,y)
        end
