The Crash Analytics reports are all limited to a set count of rows. These counts are determined by the following settings:
datatable_archiving_maximum_rows_crashes– controls the maximum number of rows in the All Crash Messages report, the New Crashes report, the Disappeared Crashes report and the Reappeared Crashes report.
datatable_archiving_maximum_rows_crash_toptable– controls the maximum number of rows for the first level table of the following reports: Crashes By Category, Crashes By First Party, Crashes By Third Party, Crashes By Page Url, Crashes By Page Title, Crashes By Source
datatable_archiving_maximum_rows_crash_subtable– controls the maximum number of rows for the subtables of the reports listed above.
If you need to see more rows in these reports, you can increase these setting values, though keep in mind, this will translate to more data stored per archive.
