Good evening B,
Just a quick note to let you know that, in collaboration with the WPML team, we have significantly improved the compatibility of our respective plugins.
You can read all about it here: https://wpml.org/build-multilingual-events-websites-events-calendar-wpml/
One of the highlights of this is the ability to use the Classic Translator (which should enable you to do what you were looking for).
I realize it has been a long while, but you are more than welcome to give it a spin.
Best regards,
Geoff B.
