Spanish urban legends is not translating

[joeysk2012]

Hello, seems like a common issue that some words are not translating on the Spanish website. In the myths and reality portion at the bottom, The header translates into spanish but the subheader remains in english. The portion of code below:

<div class="container-fluid" id="myth">
  <div class="row">
    <div class="col-sm-12">
        <h2 class="l10n" data-lkey="MythHeading">STD Myths and Facts</h2>
        <h3 class="l10n" data-lkey="MythSubHeading">Urban legends and facts about sexually transmitted diseases</h3>`

Both headers have the 110n tags but the h3 is not translating. Can anyone explain why that is?
