Hiding price in original currency for a Category

How do you hide the original currency for a product in a Category Listing? The product listing is correct, it shows the price in $600 but the category listing shows the price as $600 (£450) , I would like the category listing to just show the $600. The Default Parameters for Products has 'Show price in original currency' set to NO.

Oops I should have looked closer in the module options and set 'Show price in original currency' to No there as well as the default parameters. So the problem is now solved.
