swagger-editor: Getting undefined when giving reference to definition in response of path.

• Version: Online Swagger Editor
• Browser/OS: Browser- Chrome, OS - Windows 10

Hello, I am getting am issue from last week. I am creating documentation for my project. I am using Swagger Editor online. I have some definitions which are interrelated. Means one definition has reference of other definition. Then the response of the path has reference of the definition. But when I take a look at it in demo UI which is shown in the editor, the reference shows undefined. I have given one reference code as example . Please take a look at it in the online editor. You can see that under getUserList list in response the user definition is shown as undefined. I guess this issue is because I have references in both definitions. If I remove the userGroup reference from the user definition, I am able to see user in response. This issue wasn’t there a week before. Is anything changed ? Am I suppose to make any other changes to make it work. Please look into this issue because it is a major component of my documentation. Let me know if you need anymore details. Thankyou.
