Number Items Sometimes Given A Default Aggregate Of NONE

Question

I'm using Discoverer 10g (10.1.2.0). After incorporating an Oracle table into an EUL, I notice that several of the number type columns are given a default aggregate of <NONE> as well as the default position of TOP. And other number type columns in the same table are defaulted to SUM and DATA POINT, respectively. I have to go into the properities box and manually change these
number type columns to SUM and DATA POINT in order for them to be aggregated properly in a workbook. Why does Discoverer do this? It seems to be a random thing. There is nothing unusual between these number type columns. In fact, in the underlying table all of these columns have the data type of NUMBER.
Has anyone an idea as to why this is happening? Thank you.

AS3 requires default values to be simple "compile-time constants". The typical workaround for a case like this is to do
function myFunction(arg1:MyObject = null):void
    if (!arg1)
        arg1 = new MyObject(0, 0, 0);
