Embedded grid-edit report displays columns that are not requested

I have an application in which one table is a child to two
different parent tables.  I have linked the three tables accordingly and embedded a grid-edit report with just three fields from the child table into the custom forms of both parent tables.  I?m now trying to expand the grid-edit report to display a few more fields from the child table.  When I do this, the new fields are displayed but there are additional fields displayed which I have not requested and do not want to appear.  I have tried to fix this two different ways:

 ?        Initially, I tried specifying custom columns in the ?Columns to display? option for the grid-edit report.

?        Next, I made the desired fields the default columns for the child table and selected default columns in the ?Columns to display? option for the grid-edit report.

 In both cases the same additional fields display in the embedded report on the forms.  Is this a known issue and is there any way to force the QuickBase to not display these fields?

Any advice is appreciated.
