For any project, under Hours Tab, the total hours at the bottom shows the addition of the line items. The client's request is, it should show the addition of all the hours at the bottom of the page.
Hello @Priyanka31, The bottom right will always display the count of records. To view the total hours, you can create a grouping based on the project name or something else (see Hours column).
Please note, the grouping would show total hours on that particular page if there are more than 2000 records. To see the total hours, you can refer to the Actual Hours field in the overview form.
