Matched bets error when Betfair void bets

[Derek27]

All of the bet at the top of the graphic was matched, £2 odd was voided because it was matched after a goal. BA lists the whole bet as matched at odds of zero?

I greened-up on the Betfair site but it could have been costly if I was botting and greened a profit I didn't have. There may have been an error at Betfair's end as the market was suspended for a long time?
