this is my graph for the current month:
As you can see there's a rakeback/bonus line with about +$20.
Here are my settings for rakeback and bonus:
I've deleted the rakeback, because I don't play at that network anymore and the bonus are just a few cent from some random chests at Pokerstars. No where near the $20 the graph shows me.
So I assume that the rakeback/bonus simply ignores the date filter!?
