Require a work item with resolved approvals when delivering

I had set the precondition which requires approval for delivery

When the user is trying to deliver i expect it shows error message
"The associated work item does not meet the specified approval requirements.


it gives configuration error "The requirement for precondition are not correctly configured valid roles values are all roles specified in the process

I tested in the test project it works fine i had configured the same way doono what is missing in configuration any idea?

I have the below setup. i tried setting up for Project/Team area and roles



Team configuration--->Operational Behavior --->Deliver Server---Everyone(selected)--->Added precondition Required work item approval---added scrum master(as approver)
Team configuration--->Operational Behavior --->Deliver Server---Team Member(selected)--->Added precondition Required work item approval---added scrum master(as approver)
Even for The Team area I have setup
Operational Behavior --->Deliver Server---Team Member(selected)--->Added precondition Required work item approval---added scrum master(as approver)

Operational Behavior --->Deliver Server---Everyone(selected)--->Added precondition Required work item approval---added scrum master(as approver)
