Views classes missing in subtheme of subtheme of Zen

I am trying to create a subtheme of a subtheme of Zen. Everything is inherited appropriately, but the classes on Views display containers seem to be completely obliterated. These classes are present in the first child of Zen, but missing in that subtheme's child. The difference is seen below on line 11 in each code block. This appears to be a problem in the theme, as far as I can tell. Please provide whatever information you can to help resolve this problem. Thank you.

<div class="region region-content-bottom">
  <div id="block-views-news-block_2" class="block block-views first region-odd even region-count-1 count-6 with-block-editing">
    <div class="block-inner">
      <div class="block-top">&nbsp;</div>
          <h2 class="title"><span class="cufon cufon-canvas" style="width: 94px; height: 23px;"><canvas width="115" height="25" style="width: 115px; height: 25px; top: 1px; left: -1px;"></canvas><span class="cufon-alt">Recent </span></span><span class="cufon cufon-canvas" style="width: 68px; height: 23px;"><canvas width="84" height="25" style="width: 84px; height: 25px; top: 1px; left: -1px;"></canvas><span class="cufon-alt">News</span></span></h2>  
      
      <div class="content">
        <div class="views_view view view-news view-id-news view-display-id-block_2 view-dom-id-5">
