Customfields - textinput field, how to remove "Price: " ?

[ufo_hk]

Hi,

I'm using a number of textinput customfields on one of my product pages to collect information from customers.
However I have no need to charge "per letter" or "per input" so enter "0" as value for the customfield.

But I still get  "Price:$0" showing up on the product page under the customfield.

Is there a way to hide this test from the product details page?

Issue is on this page:
