Stock sale skews balance sheet by commission amount

[TRunner]

I'm not sure exactly what my mistake here is, but if someone can  
point it out it would be very helpful.

After this stock sale transaction, my balance sheet is off by $34  
(I'm sure it's not coincidental that's the commission amount), but  
the transaction itself balances, so I don't know what I'm doing wrong.

Expense:Investment:Commission			buy 34.00
Assets:Investments:brokerage				buy 3269.68
Expense:Capital Loss						buy 713.32
Assets:Investments:brokerage:fund              -580.612 shares @ 5.69	 
sell 3303.68
Assets:Investments:brokerage:fund  								sell 713.32
