When you right click the mastery reward and increase the automatic leveling option where you pay diamonds for levels, when you have a mixed reward 'ie 600 gems and EoE boosters' or '4000 gold and Lorwyn boosters' it shows 600 EoE boosters and 4000 Lorwyn boosters instead of the correct values at the bottom of the screen. This is clearly incorrect but could be very misleading to newer players.
