columns hidden by large column groupings

 

Above is a screen shot of the issue I am seeing with my report control.

The "gutter" spacing produced by the column grouping is hidding some of my columns.

 

When they choose to group by a specific column should I be adjusting the columns some how.  I would think it would happen automatically.  I could be overriding something that would do this normally... but I don't know.

 

Thanks
