@marcobecker, you can set that to ‘ignore’. The field doesn’t need to be translated.
We also made a modification in our WPML configuration repository for WooCommerce Multilingual and this field. This usually takes some time to propagate automatically.
Once the change becomes available in our repository, you should be able to activate it manually too at Dashboard->Updates->Theme and Plugins compatibility with WPML. Or wait for the daily cron to run that for you.
