When assigning names in the wizard you may find you need to change a reference either made by you or automatically assigned.

The instructions tell us that pressing delete does this. I have not found this to be the case. I have found that if one presses delete and then Enter the item is removed.

There is however one quirk in that the focus may jump up or down the list to some other point. So far this has been only a few rows away but is a little disconcerting.
