Multi Variants URL does not maintain a structure..

[MSpencer141]

Hi,

I've come across a strange scenario... please see (I have purposely turned off SEO Friendly URLs):

http://www.kitlocker.com/joomla_new1/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=1&virtuemart_category_id=167

When you change the colour of the item at first the URL changes fine but there after when changing colour or size the URL begins to go strange - overwriting the URL with colours and sizes,

Any help would be much appreciated..

Many thanks,
