When Proxy Bidding is in effect, it can appear as if one bidder has beat another bidder with the same bid amount. This is normal and occurs when a bidder has a proxy bid in effect and a second bidder comes along and makes their bid at the exact same amount the current proxy bid is at. Since the proxy bid was placed earlier, that is the bid that will succeed. For the second bidder to succeed in placing a bid, they must bid higher than the proxy bid that is in effect.
