Payment & receipt form

In payment and in receipt form in the line where you have to select Other or Customer or Supplier (payee an Paid by), all the drop lists appear (the fields are apparently not anymore conditioned to the selection)
It seems anormal comportment? if so what is the interest of this change? as it is complicating a lot the form filling…
