Lowering the bid in auction

The game throws me out the auction building if I press delete to change a bid of a player. This is not because I am the highest bidder and want to lower my current active bid, it comes about if I have a bid for example of 900 on a player, but I am winning the bid with 300; I cannot lower the 900 to 400.
Ya I see its not like it used to be. You manually have to input the new bid now..
