Missing content from blog posts

Hello,

I have recently implemented the plugin to my website and I noticed that some paragraphs are missing from the blog posts. Please check the link above and let me know of any possible solution.
Also, when a user chooses the second language on the main page, then he has to repeat his option on every single page. Is there any setting that can remember the user’s choice?

The page I need help with: [log in to see the link]
