The reason why this occurred was a setting called “change auction duration when a bid is placed” was ticked in the administrative settings of the auction platform. This changed the duration of the first share auctions shortening them which was unexpected by prospective buyers and sellers. This issue had not been noted by myself during the beta testing I did with trial users last year. I have now disabled this setting so it does not cause the same problem again in future share auctions.
