I don't see their plugin on our official WPML-compatible plugins repository here (https://wpml.org/plugin) and I don't know of any news from them making their plugin fully WPML-compatible.
Probably it would be best to reach their support to see if you can find any extra information on this matter.
This is the best response I can give at this point taking into consideration the data that I have.
