Duplication URL categories

[RomkaSom]

There is a site http://www.gastronomik.ru/ by Joomla! VirtueMart 2.6.12.2 and 2.5.28

On Joomle includes:
Enable SEF ( NC )
URL redirection
Add a suffix to the URL
Aliases in Unicode

In Virtuemart SEO is also included

The problem itself :

If you go to the menu such as meat will link http://www.gastronomik.ru/myasnoe.html
Then if you go into the meat (there is another category ) that will link http://www.gastronomik.ru/myasnoe/myasnoe/myaso.html - and displays all the stupid store goods .

But if in the menu, then go all the rules work.
Already hesitated to fight (((
