"Read more" goes to home page

Hi,
I have a problem with "read more" button.

The button goes to home page instead of the article.

URL : http://umbrella.efqm.pl/

There is a module "O NAS" at the bottom. It is Module News Show Pro GK4 with one article defined by article ID.

The button generates URL mySite.com/index.php/id-category_alias/id-article_alias

This URL goes to home site.

When I open the same article form menu item the url is mySite.com/index.php/article_alias and works fine.

What is wrong ?

Kind regards,
Marcin

Please make sure that articles displayed in News Show Pro is related with some existing menu item, if not Joomla! can't generate proper URL to this view.
