Change label "Item price" in K2 item presentation

Hi
when I see the details of a K2 item I see the label "Item price" before the price of the Item.
Now let's say that I want a different label for that e.g. "Price". How can I change that?
The only label "Item price" that I have found in the language files is in the en-GB.mod_news_pro_gk4.ini file and changing that does no good...
Please respond and thank you for your time

Hi,

In my installation I don't see that label somehow, here is my screenshot of a K2 item http://easycaptures.com/fs/uploaded/434/2400756687.jpg
