[v4] EasyDiscuss Category module does not respect language of the site.

I am trying to upgrade my site to EasyDiscuss v4 but I have faced a lots of issues regarding to multilingual support. Here is one of them: EasyDiscuss Category module does not respect language of the site. I have multiple categories in multiple languages but the module shows up all the categories no matter whatever the current site language is. Please fix it as soon as possible. Tks!
