错误消息重复多次引导和jQuery验证表单

对于我的注册表单，我使用bootstrap 3和jQuery Validation插件。除了每次用户单击字段时都会重复出现错误消息之外，其他一切都很好。我检查了一些工作示例，没有发现与我的代码有任何不同。我还试图删除（）或隐藏（）错误消息，但仍然存在。有什么解决的建议吗？

<form accept-charset="UTF-8" method="post" action="form.php" class="form-inline" novalidate="novalidate">
        <div class="row col-md-10">
            <label for="name" class="control-label">Full name*</label>
            <input type="text" class="form-control" id="name" name="name"> 
            <label for="email" class="control-label">E-mail*</label>
            <input type="email" class="form-control" id="email" name="email" placeholder="e.g. yourname@work.com, yourname@university.com, ..."> 
            <label for="city" class="control-label">City*</label>
            <input type="text" class="form-control" id="country" name="country" data-validation="country" data-toggle="tooltip" data-placement="right" title="" data-original-title="Why we need your city? We aim to match people on a regional basis. Although this is done for ensuring convenient times as most contact is usually via phone or video." name="city">
            <label for="zipcode"> Zip code </label>
            <input type="text" class="ignore form-control zipcode" name="zipcode">
        </div>  
        <div class="row col-md-10">
          <label for="currently_employed" class="control-label currently_employed"> Are you in current employment?* </label>
          <ul class="options">
            <li>
              <input type="radio" class="form-control" id="user_currently_employed_true" name="currently_employed" value="true" /> 
              <label for="currently_employed_true" class="control-label"> Yes </label>
            </li>
            <li>
              <input type="radio" class="form-control" id="user_currently_employed_false" name="currently_employed" value="false" />
              <label for="currently_employed_false" class="control-label"> No </label>
            </li>
          </ul>
          <div class="clear"></div>
          <label for="company" class="control-label"> Your Company/University* </label>
          <input type="text" class="form-control" name="company"/>
  </div>
  [....]
</form>
