J-BusinessDirectory - Automatic switch-over to the product page on the default language

Help! 
I have a website in two languages (English and Russian). the default website language is Russian. 

On the English version of the site pages, when you navigate to the page of the enterprise, automatically switches the language to Russian. also, if the default language angliski, on the Russian page of the company's switch to English. 

What to do? how to solve this problem?

the problem is on all templates, including the standard in Joomla
 J-BusinessDirectory - version 4.3.4 
Joomla! 3.4.8

Hi,

This issue should be fixed by turning SEO to no on general settings of directory.
