The Tournament Director doesn't consider this a bounty that you "won", it's actually categorized as a bounty you "kept". It is not included in your bounty winnings, but it IS included in your total winnings.
I suspect this is an issue you might want to raise on the Stats Genie site - see if this amount should be included in the "Knockout revenue" field for a player. I could easily make this change, but that would affect everyone who uses this feature.
In the meantime, you can adjust this yourself by editing the exported file. It's in XML format. Just look for the player and edit the KnockoutRevenue attribute:
<Player Name="Andrew D" FirstName="" LastName="" Rank="1" TournamentPts="5" Buyin="50" Rebuy="0" Addon="0" Payout="250" Knockouts="1" KnockoutRevenue="5" BountyCost="5" RoundOut="" TimeOut=""/>
Change KnockoutRevenue="5" to KnockoutRevenue="10", for example.
