Got stuck at a particular league activity.

I've been active, grinding and playing all matches and events necessary since this current event, but at a point, my activity points got stuck without moving anymore, this happened since 23rd of this month (November). Am at 2470 activity points already, but since then that I've be playing more and grinding more, I check my activity points, it's not increasing since that Saturday, why?.
