Conversation Label

I tried to change the conversation label to show "Patient_Name" from the default "New User". When I went into client access for the agent id: agent_058187b00bcb36dd8c97eaaa1 I selected "customAnalysis.Patients_Name" because I saw no Metadata options like you showed in your training video. This did not work after saving it didn't change the conversation label when I did a test call. Can you assist on what I'm doing wrong. Shouldn’t I be able to pull this from the extraction items I set up in Retell. If it needs to have metedata in front of Patient_Name, how do I do this. Thank you for your assistance.
