Do you happen to be running WP SSO as well? I had that multiple other problem caused by a setting from that plugin. Yoast was also installed so it may have been a 3 way conflict.
My issue was resolved by disabling “Apply WordPress Content Filters” at SSO Pro –> Advanced Settings –> Content and Filters.
So give that a shot if you happen to have the same plugins. Gravity Forms, WP SSO and Yoast.
That sounds like a plugin or theme conflict. Can you try and gather as much information for us as possible? Please perform the following:
1. Make sure the issue doesn’t persist when Yoast SEO is disabled.
2. Check for conflicts.
3. Check for JavaScript errors with your console.
If you find any JavaScript errors related to Yoast SEO or if there is a conflict with a plugin or a theme, you can create a new GitHub issue for our developers. Please report the issue to a third party developer as well.
If you didn’t find any conflicts or errors, we think the issue is specific to your site. We’d need to investigate further but are unable to do so on these forums. You can purchase Yoast SEO Premium and receive our Premium email support and we can help you further.
