Removing Product Code from listing title

Please help help guys I really need to be able to remove the product code from my h1 product title in the singular product view. Please Help.

I've checked the hikashop demo site with fire bug and am seeing class declarations in the html that aren't in my product view html. For example, there is a product_title class and product_code class and the class has a display none style declaration.

Where as on my site there is no product_title class or any product_code class in the resulting html. My assumption is that the php file that builds the product view needs to be amended. I can't seem to find any setting in the Hikashop backend user interface that corresponds with the product code's display in the layout view. Any help would be greatly appreciated as I don't have a lot experience with javascripting.

@Nicolas I had two templates running on my site, my home template and internal template. When I disabled the home template the problem went away. Have you encountered any problems with the Hikashop display in the past being affected when multiple templates are being used across a site? Hikashop was only published in the internal template so I'm not sure why unassigning the home template would affect how the product displays in the product view. In any event thanks for your reply.
