Hi Mohita,
We have upgraded from ActiveReports 7, where these reports worked fine.
KeepTogether of the sections to was already set to True. This issue shows in many reports, I attaching a screenshot of a simple report with this issue. The detail section is narrow and will not overflow.
Also, blank pages in the report appear as single pages or many (sometimes 10-20) in a row.
Thank you,
Adam
