我有麻烦让猫头鹰旋转木马主题样式表对我的滑块有任何影响？

我使用的是最新版本的owl.carousel.2.0.0-beta.3

这里是我的测试地点：示例网站

下面是与owl旋转木马相关的HTML代码：

<div id="owl-single" class="owl-carousel col-xs-12 owl-loaded owl-drag">

  <div class="owl-stage-outer">

    <div class="owl-stage" style="transform: translate3d(-1396px, 0px, 0px); transition: 0s; width: 4886px;">

      <div class="owl-item cloned" style="width: 698px;">
        <div class="item">
          <img src="img/slide2.jpg" alt="GTA V">
        </div>
      </div>
      <div class="owl-item cloned" style="width: 698px;">
        <div class="item">
          <img src="img/slide3.jpg" alt="Mirror Edge">
        </div>
      </div>
      <div class="owl-item active" style="width: 698px;">
        <div class="item">
          <img src="img/slide1.jpg" alt="The Last of us">
        </div>
      </div>
      <div class="owl-item" style="width: 698px;">
        <div class="item">
          <img src="img/slide2.jpg" alt="GTA V">
        </div>
      </div>
      <div class="owl-item" style="width: 698px;">
        <div class="item">
          <img src="img/slide3.jpg" alt="Mirror Edge">
        </div>
      </div>
      <div class="owl-item cloned" style="width: 698px;">
        <div class="item">
          <img src="img/slide1.jpg" alt="The Last of us">
        </div>
      </div>
      <div class="owl-item cloned" style="width: 698px;">
        <div class="item">
          <img src="img/slide2.jpg" alt="GTA V">
        </div>
      </div>
    </div>
  </div>

  <div class="owl-nav">
    <div class="owl-prev">prev</div>
    <div class="owl-next">next</div>
  </div>

  <div class="owl-dots">
    <div class="owl-dot active"><span></span></div>
    <div class="owl-dot"><span></span></div>
    <div class="owl-dot"><span></span></div>
  </div>

</div>

名为“owl.theme.default.min.css”的样式表看起来包含了所有的导航样式表，但由于某种原因，它没有对PREV和NEXT按钮进行样式化？

如有任何帮助，我们将不胜感激。
