Research direction
Investigate the diagnostic page for database usage, likely in the Piwik/Diagnostic directory. The issue shows a discrepancy between SQL counts and displayed counts. Check if the query used for display is correct (e.g., maybe it includes deleted or filtered records). Look at the Controller and View files for the General Information section under Diagnostics > Database Usage. The solution may involve updating the query to match the actual count from the statistics tables.
