Underlay fallowing sections

Hi All,

I have a report having group on product name.and in group footer i have some summary .

I have some fixed length for product name group filed. i checked underlay fallowing section for that group to show with details section.

Whenever the p name is more then the length field it should show in next-line and it is working fine.

But the problem is whenever is having only one row for details section it is giving some space for group header .i don't want that.

Please suggest and PFA for report and screenshot.

In the attachment for Guardian Mini Lock Group the summary which is in red color coming in next linbe.

I want that also in same line of group header please suggest.
