UI glitch with the new Leaderboard

The [X] button is beyond reach, in my fairly small screen resolution (1280x720). Resizing the browser window makes the [X] button partially visible, so it can be clicked. It would be nice if there was an alternative way of closing the window, like pressing the Escape keyboard key. I am using the Brave browser.

Button [X] visible:

Same problem here. 

I also don't have the X button and I didn't even know that it's supposed to appear in 2 columns

quick workaround for now: If your on a pc easy way (until they find a fix) is just hold down ctrl button and then hit the - key "ctrl -" and it will shrink it so you can see x then if you want to go back do same thing but ctrl +
