Not able to add rtf template in Compensation Change Statements task in Plan Configuration

Summary: I am not able to add rtf templates in the "Compensation Change Statement" task in the WFC plan configuration

Content (required): I have a new instance where i am creating a WFC plan. I have completed all the steps and the plan is working as expected. Now i am trying to add a rtf for the Compensation Change Statement in this newly provisioned instance. However, When i click on "Manage Statement Groups" button on the Compensation Change Statement task, the system is not allowing me to add an rtf statement over there and giving me error. I have attached the error screenshots.
