Yeah, the default Due perspective they provide only shows you things within the radius of the "Due Soon" setting, due to the overloading of the "Due Soon" setting (an unfortunate design decision, I think). Fortunately, you can undo much of the damage by editing the Due perspective to use "Any Status" as the value in the Status Filter instead of "Due Soon". Once you've done that, save the perspective as the Due perspective and you can see upcoming due items, no matter how distant.
