you might try deleting the first figure before adding another. one other thing it might be is that you are trying to add a figure, but poser thinks you are trying to replace one. instead of double clicking the new character as you would expect, single click it, and go to the bottom where you see a double check mark, and click that. then you can have two figures in the document window simultaneously. old hats at poser tend to forget that simple stuff like that frustrated us once upon a time....
