Why is there a minus on some transactions?

I've just looked at my EPN transaction report for the last 2 days and there's a minus on some of the transactions, it's the first time I'm seeing this and I check the transactions every few days. And no the winner isn't the same user.
example
item sold for 65 and I see -3.60

The auction failed and egay had to pay back the seller fees, so they take away your earned money as well.

Oh, alright. Thanks for the quick reply bud, I was thinking it was something like that.

noticed this on the epn blog:

Reporting Issue on August 10th
August 15th, 2008

Hi all,

On Sunday, August 10th we had an issue that affected reporting of eBay Total Sale Amount, Earnings, and EPC in the US, UK, AU, and CA programs. These metrics were double-counted for certain items, so some publishers will see overstated earnings amounts for August 10th. Affected publishers will notice an update in their summary reports on August 18th to reflect the correct amounts, as well as line items in their transaction download report to debit the overstated amounts. These line items will include the eBay Item IDs that correspond to the overstated amounts and will contain August 10th Transaction Dates.

We apologize for any inconvenience this reporting error has caused and thank you for your support of eBay Partner Network!

Hope this helps explain the minus charges
