Ensure you have the latest version via composer update.

If issue persists, it seems your environment has outdated web assets / stale cache - you need to clean your web runtime assets and also the browser cache and hard refresh browsers and retry. You can check that the updated version works fine on the demo site. Cross check the basic demo example here.
