we don't know what does not show up on your end but if you look at http://pasteboard.co/eLEvsX7Zj.png you see that the icon is fine. We checked on 5 different computers in different browsers with same result what means this must be cache on your end.
The screenshot we gave you above came from iOS but in Windows it looks exactly the same. And of course we checked in different browsers. We recommend to clear your cache because this must be the reason why it does not show up on your computer.
