Integration with FB Group to WP plugin

We’ve been using Polylang for a while and recently decided that it would be great to import our Facebook posts to the blog, so they appear as blog posts. For this we’re using FB Group to WP plugin, https://sv.www.ads-software.com/plugins/fb-group-to-wp/. The problem we’re having is that the facebook posts aren’t appearing on the blog, they’re hidden from view and my theory is this is because they’re not assigned a language. Does anyone have experience of using both plugins together, successfully?
