"Next " button not working in Dashlets ( Suite CRM )

When we have more records in Dashlet, "Next" button is not working. Version 7.6.4.

This Dashlet is from reports module.

On click of next button:

index.php?module=AOR_Reports&record=9553e1a0-929a-9895-20ac-57518527f3cf&offset=20&table_id=&parameter_id=&parameter_operator=&parameter_type=&parameter_value=&action=changeReportPage

is getting called but Dashlet is not displaying next records.
