Amounts claimed by BDC on invoices

My "Finance" sections says I owe BDC funds from months ago.  As far as I am aware I havent had any cancelations or not cancelations outside my policy so I dont understand why I owe this amount.

Plesed to note BDC has employed an accountant to look at the billings remittances documents.  To me a chartered accountant(but what would they know) wouldnt have ever called a remittance an invoice but they sorted that out a few months back.
