[Frank K.]

I mean the span-Tags that wraps such values as
###PRODUCT_TITLE###

<span class="com_prod_title">Wienerschnitzel</span>

they are generated and don't appear in the template.But I don't know whether 
they are made by the commerce or by the css-styled-content extension?and how 
to remove them ....?
