That report module is an out-of-the-box/built-in report. It has a few filters on it which might be a problem for your custom report that attempts to recreate the built-in module since you are not using any filters.
The built-in report filters on the following:
1. Ticket has a status CLASS of Completed or On Hold (do not include Cancelled)
2. Ticket Last Modified Date > Ticket Closed Date or Ticket Last Modified Date > Ticket On Hold Date
It is also ordered by Last Modified Date in descending order.
You would need similar filters, and also you'll want to have the report return more than 500 rows. The maximum number of rows allowed is 50,000.
Please let me know if this helps you to create your report and return the desired results.
