Hi I wonder if you can help.  i am wanting to make the above theme Lusion multilingual and there is a button to do that. but i cannot find where i even start to modify this section and add additional languages etc.  

i have tried installing WPML and Weglot - unfortunately, both seem to have adverse effects on the site, with some functionality disappearing.  other people seem to talk about their sites being in multi language, but i dont even know where to start here.
