QuickBooks stock entries

Dear QuickBooks gurus,

Please see this image, which is the "journal" report for a purchase (accounts payable) invoice.

The gross payable is £98.45. That should be the end of the story - but QB has created an entry of 54p between Stock Asset and Cost of Goods Sold.

Can anyone explain what this 54p is all about?

Thanks,

Adrian
