Applying discount, but none set up!?

Hello, now the order display has suddently started doing something odd... it was fine before, no idea what might have changed, but it is now showing

SKU             Product Name    Product status    Price    Qty           Discount         Total
156705    ZAO orbit brush    Confirmed           R 95.61   1           R -0.00    R 109.00

See the "R109" that shows twice for first item. In e-mails and invoices it shows like this. In the order view online in the shop it shows the first "R109" with a strike-through, the second normal, like a discount has been applied. We have no discounts set up. Where could this error be? The other calculations and totals are fine - just shows double for some reason, but not considered double in calculation, so total is correct.
