The WPML support said today:

Draw your own conclusions…
Edit: The technical background is explained here:
Summary: WPML 3.1.7+ downloads a remote config from WPML server which currently tells WPML that ACF can not be translated. The update of this remote config is triggered at every
activated_plugin wordpress action and at custom wpml-actions.
