Page sections occupy the same space on each page, even if they are hidden - Understanding Rendering Behaviors
There is an approved feature request for having varying page sections per page, which you can vote for in order to raise its priority - ability for report header to reclaim empty space left by conditional formatting
. Note that the task involves changes in the core mechanism of the reporting engine and it is not that trivial.
As a workaround, I can suggest you to combine different reports into a single document via ReportBook
. This allows you to have different page settings per report - Page Settings, Sizes and Naming
