模态显示在导航栏和背景下方

Question

我正在尝试为我的更新按钮创建一个弹出模式。 Idk出了什么问题，但其模态显示在导航栏和淡入淡出的背景下。有谁知道如何修理它？另外，我还有另一个带有模式的按钮，它工作得很好。

是这样的： 这是我的模式代码：

<div class="modal fade" id="ModalUpdateUser<?php echo $data_user['id_user'];?>" tabindex="-1" role="dialog"
  aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">

      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span
            aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="ModalUpdate">Update Data</h4>
      </div>

      <div class="modal-body">

        <form method="POST" class="cmxform" action="act_user/update_user.php">

          <?php
                   include 'koneksi.php';
                   $idupt = $data_user['id_user'];
                   $q_update = "SELECT * FROM user WHERE id_user = '$idupt'";
                   $sql_update = mysqli_query($dbcon, $q_update);
                   while($update = mysqli_fetch_array($sql_update)) {
                   ?>

          <div class="col-md-6">
