Boss fight promoter bonus not added for event

I won 4 lvl 10 matches.

I got 4100 coins for first time victory, 4100 coins for faction bonus on each match. In 2 matches i used boss promoter and got 1230 coins on each of them.

So i gained total of (4100*8) + (1230*2) = 35260.

So my event points should have been (35,260×200)+4,000 = 7,056,000.

But my event score is only 6,564,000. This is because coins i gained from promoter bonus is not added for the event. Why is that? I need those missing points to claim my last reward.
