Unable to pipe embedded data in to action email body

Hi, I am trying to pipe embedded data in to the body of an email (action), which I am using to test a Salesforce Workflow Action. Basically, I want the action to send me an email with all of the embedded data received from Salesforce so that I can check that we are receiving all of the data correctly. When I attempt to pipe in the embedded data fields in to the email body, the 'pipe text' icon says 'No items to display' (see image attached). I am also unable to tick the 'include response report' tickbox. I have set up the embedded data in the survey flow correctly, so i'm not sure what the issue is. Any help much appreciated! Thanks!
