Pages are set to flow Direction Top to bottom and page breaks are allowed within the page
The subforms on the page are set content: positioned, auto fit in height.
So is there a way to avoid unwanted creation of the gaps?
I guess the subforms might have some value specified for either "Top Margin" or "Bottom Margin" or both. Please check. If the issue is not yet resolved, please mail the form to firstname.lastname@example.org
