The totals of points on the top of each column are blinking each 2" : the number disappears a short time, it's visible.

Is the title text of the column is short, the total number is displayed under the title. But the previous blinking problem, when the total text disappears, the eight of title decrease, and all the column content move up and down (when the text appears)
