Can’t delete a bid

Somebody mistakenly put a bid at $2600.00 instead of $26.00
I’m trying to remove the bid. I edit the item and go where I see the bids and hit delete. NOTHING HAPPENS. It does nothing, goes nowhere. The link it shows when I put the mouse over is https://optimistclubofcornwall.org/wp-admin/post.php?post=3211&action=edit# and that does not work.
