Unable to find Person Name while creating Create Unprocessed Cost expenditure batch

Hello Experts,

I have created the Unprocessed Cost batch to capture labor expenses under the Expenditure Type "Labor". However, I am unable to search/select any employee to capture the labor cost.

I have looked at Resource Pool and Project Enterprise Resources, and the setup looks fine.

I am unable to select the employee, in Labor Cost spreadsheet also. I have attached the screenshot of issue for reference.

Please help to troubleshoot how to capture labor cost for employee.
