Looks like you are using a template override there? In which case check the code in [yourjoomlatemplate]/html/com_virtuemart/category/default.php (compare with components/com_virtuemart/views/category/tmpl/default.php )
Hey :)
Yes, you where right there was template override.
I solved my issue.
Thank You!
