XP or Match History bug

This evening I played a normal draft game as Olaf and won, counting for my First Win of the Day.

At the end of game screen I thought it said I earned around 700-something XP (can't recall exactly) which sounds about right for a win with FWotD.

Looking at my match history now, it says I earned EXACTLY 575 XP from that game. For a FWotD that's obviously too low and without any other XP bonuses it's obviously too high.

Did I earn the correct XP value? Is my match history bugged?
