Headers are displayed if there is no space to display data on a page

Hi,

I have a report with many sub-reports. Each sub-report has data displayed in a tabular format. I am exporting the report in PDF Format. When I export the report to PDF, some sub-reports print just the header as there is not enough space to print the data on the page. The header and data printed properly in the next page. I wish to print the sub-report only when there is enough space to print atleast one row of data on the page. Is there any way to achieve this in Jaspersoft Studio. I am using Jaspersoft Studio 5.5.

I have attached the image of the issue I am facing.

Thanks in advance!!!
