Bets vanishing then reappearing.

Something strange happened this morning. It worked out OK, but by fluke. I put 3 bets on the Inter Miami match with a view to trading out after a goal. All three bets were definitely matched, but when Miami equalised all 3 bets disappeared and my balance went back to what it was before. Tried different devices but it just wasn't there. One hour after the match I checked again and my balance had increased as 2 of my 3 bets had won (Miami had won 3-1) If the match had finished 1-1 or 1-2 I would have made a loss through not greening up. I should be thankful for the bonus profit, but it's a bit worrying. Has this happened to anyone else?
