This issue occurs when grouping transactions by commitment. 

The nature of a relational database is that parent-child records must always be grouped together.  When there is a parent record such as a recurring gift that has a large number of associated child records (such as 100 recurring gift payments), all of those payments must be listed as associated with the parent.  If the payments were separated into multiple pages, then some payments would appear to be disassociated with the parent record.
