Switch value in uifigure is inverted

Hi,

The following function taken from https://www.mathworks.com/help/matlab/ref/uiswitch.html doesn't behave as expected in Matlab 2020a

"Switch That Changes Lamp Color"

function lampswitch
fig = uifigure('Position',[100 100 370 280]);


lmp = uilamp(fig,...
    'Position',[165 75 20 20],...
    'Color','green');


sw = uiswitch(fig,'toggle',...
    'Items',{'Go','Stop'},...    
    'Position',[165 160 20 45],...
    'ValueChangedFcn',@switchMoved); 

% ValueChangedFcn callback
function switchMoved(src,event)  
    switch src.Value
        case 'Go'
            lmp.Color = 'green';
        case 'Stop'
            lmp.Color = 'red';
        end
    end
end

The switch value is somehow inverted! Lamp is red when switch is on "Go"(see video here https://www.dropbox.com/s/ms4lrk0x4q88sle/VID_20200704_123830.mp4?dl=0). Sorry for the low quality.

I see what you mean in your video...

The code does work properly on my system though.

I imagined it was something with my machine, but I have no idea what.

Reinstallaed Matlab and everything went back to normal.

After receiving an error while working on this app, this weird bug appeared again and now all the switches work in the opposite way. Really frustrating!

I did further testing: only the uilamps object are affected, other code inside the switch case statements work fine.

Strange!
