Redirect to curent translation page

Please tell me how the redirect to translate of current page. Now I choose another language and it redirect me to the Main page. Example:
– Now mysite.com/category/postname1/ when choosing a language, is redirect to mysite.com/en/
– How it should be mysite.com/category/postname1/ at mysite.com/en/category/postname1/

Or this plugin not support this redirects?

Thanks
