Where are Survey settings in Webinar

In the documentation, it says that here are settings in the Survey tab which allow you to check whether you want a pop-up survey or a link in the follow up email. (see below) There is no "Survey Options" setting in my webinar Survey tab. What am I missing? 

1. Scroll down to the bottom of the page and click the Survey tab.
2. Next to Survey Options, click Edit, and select any of the following check boxes:
   • Show in the browser when the webinar ends: Display the survey in a browser when the webinar ends.
   • Show the link on the follow-up email
3. Click Save to make the change.

Thanks,
Mary
