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.
