Payments to Loans to show as Auto Category

Hi all - quick question, as I must be missing something.

I have an auto loan setup. Each month, it creates a transaction in my checking account for the monthly payment. Let's say it's $500. The payment is split, with $400 going against the [Auto Loan] account and $100 in the interest expense category. That works fine. I also have a lease on another car, which is $250, which is against the expense category Auto. Also works fine.

However, when I look at planning/budgets, it only shows the lease payment of $250 as my auto expenses for the month. It *should* show the $250+$500 = $750, because that's my auto budget for the month. (Alternately, it could show $650 auto and $100 to loan interest - that also would be accurate).

Any ideas?

Thanks,
Will
