Displaying Contract Total with CO in report

Hello Community,

I have a requirement where I would like to display the Contract Total in the report from the Retainage Section --> Summary tab --> Projects form.

I have added the PMProjectRevenueTotal.CuryRevisedAmount. But if the Include CO checkbox is selected, the field doesn't include the calculated amount. As below: 

When Include CO checkbox isn't selected :

And the report shows the following amount:

Now when I active the checkbox, the amount changes to,:

But the report still displays:9,862,000

How can I get this done?,
