No trick. You clicked on the pink icon, right?
Edit: if you're seriously stuck, right click on the pink icon and select "Inspect Element."
You'll see something like this in the highlighted portion of the source HTML:
width="18" height="18" title="Tournament game" alt="Tournament game">
Scroll just above that (without expanding/shrinking anything) and make sure you see something like this:
If it's there, then the icon should be clickable. And of course, the tournament ID in the link should be the ID of your tournament, not CSL China 2v2 (unless you're somehow looking at a game from that tournament).
