Hope someone can answer this.

I've just watched a match in my league and the game ended in a 0-0 draw which was a great result for me but when I came out of the match and into the League screen the score still said 0-0 but then (infront of my eyes) the score changed to 0-1 in favour of the team that I didn't to win.

WTF is going and can anyone shed any light on why it happened? 😡😡😡😡😡
