WPML problem

Hi
I have strange problem. On blog pages I’m using separate shortcodes to show certain categories in two languages. However when I use category in shortcode, the content is not translated after language switch. Using category_in shows “no posts” on language switch. All loads fine after I refresh page. Load more loads fine as well. Any idea? Thanks in advance ??
