Report Builder 1.0 and MandatoryFilter

We are currently using ReportBuilder 1.0 (2005).

I don't understand how the MandatoryFilter setting works. It does not always ask for a filter only when certain fields are included in the report and only when they are selected in a certain way.

For example, if I double click on an object, it will add all all unused fields to the report. This calls the filter.

Adding the same fields by clicking on the fields does not ask for a filter.

This seems inconsistent.

In addition, double clicking on an object gives fields that are under one tab, which is labeled with the table name. If I just click on the fields, they each have a tab with the field name. Does it matter?

I tried asking on the MS forums but no answer.
