prev/next_post_link return links to articles without translation

What i have:
1) WP v 4.1.1
2) qTranslate-X 3.2.7
3) qTranslate options http://goo.gl/l76h9P
4) Custom post type ‘blog’
5) Not all articles translated
6) in the single-blog.php I call
previous_post_link(‘%link’, ‘%title’);
next_post_link(‘%link’, ‘%title’);

But i have problem:
in result Displays a link to an article default language that has no translation.

I want to get a result that provides a link to the article only with the translation.
What could be the solution?
