Hi,
I'm not sure which one you're talking about. There are two selectors with the same name 'our_price_display', but both have different selectors. The first one using class, and the other using ID. This is not something you should worry about.
<div class="price bordercolor">
<span class="our_price_display">
<span class="price" id="our_price_display">99,99 Ron</span>
Cheers
