Clash of Code Leader Board

I just hit 39th in the US on clash of code. I was looking at the leader board. This might be a bug, but there isn’t any headings showing up to tell me what each column is. I’m really just wondering what the 2nd column is.

The second column is your rank and username. I guess you didn’t want to ask that.
Third is the points (you get points for winning and lose points for losing a clash or being inactive).
Fourth: number of participations
