Expected behavior

Correct markup in Panels section of premium admin template as pointed in https://mdbootstrap.com/docs/jquery/components/panels/

<div class="card">
      <div class="card-body">
        <h5 class="card-title">Panel title</h5>
     </div>     
</div>

Actual behavior

Wrong markup in Panels section of premium admin template at https://mdbootstrap.com/previews/templates/admin-dashboard/html/components/panels.html (Basic examples topic)

<div class="card card-body">
  <h4 class="card-title">Panel title</h4>              
</div>

This confused me since i used this code as reference
