I'll provide a little bit more context to Rich's statement.
When you install the latest version of the developer's edition of the Experience builder it is going to be built on the latest JavaScript SDK and ArcGIS Enterprise. Because you are using an older version of the ArcGIS Enterprise than the one it was built on you may run into some features like this that weren't exposed to the JavaScript SDK at your older release of ArcGIS Enterprise.
The first network management release to include the new ArcGIS Advanced Editing user type extension will be ArcGIS Enterprise 11.3, which releases later this year.
