Need help with group headers on a label report layout

I am having an issue with using grouping on a label report. The structure of the report is very important to maintain the integrity of the layout. When I add grouping to the report, it adds a group header which moves the details of the report down the page a bit and changes my layout. This causes some of the content of the label to run off the bottom of the label. Is there a way to group and sort without crystal reports adding the group header and changing my layout?
