incorrect display of product title in widget results using qtranslate-x

Hi,

I am using qtranslate-x plugin (because standard qtranslate and mqtranslate are out of date) and tried to use this plugin as a widget, but in suggested search results there is an untranslated title displayed as shortcode format (please see the screenshot here).
Any ideas why and how to fix it?
By the way I have an idea to add a filter to the filters array of qTranslate support for WooCommerce plugin but I have to know the right variable first.

Thank you in advance.
