我的tabbable窗格有问题。当我加载页面时，第一个窗格通过pageload保持为空。当我切换到第二个窗格并返回第一个窗格时。显示内容。我找不到解决方案，没有javacript错误，但我认为这必须是一个javasript问题。我正在使用bootstrap 4 alpha 6和jquery3.1.1。还有wow.js，jquery.easing和tether这里是我的代码：
<div class="tabbable-panes">
<ul id="clothing-nav" class="nav nav-tabs" role="tablist">
<li class="nav-item">
<a class="nav-link active" href="#home" id="home-tab" role="tab" data-toggle="tab" aria-controls="home" aria-expanded="true">Button Groups</a>

<li class="nav-item">
<a class="nav-link" href="#hats" role="tab" id="hats-tab" data-toggle="tab" aria-controls="hats">Button Toolbar</a>
</li>
<!-- Dropdown -->
