Duplicated DOM values for the "csrf_token" in login.html

I got some odd thing in my DOM for login view. For some reason, my form has the additional field with csrf_token data. However, it has already existed as the input field out of form. The problem is that I have useless div block in my form with duplicated data. Is it the appropriate behavior of flask forms? My Python code below: <form name="login_form" action="" method="POST" class="form"> <label>Please, enter your login data</label> {{ form.hidden_tag() }} {% for field in form %} {{ render_field(field) }} {% endfor %} <button type="submit" id="submit">Login</button> </form>

HTML responce of my form below: <form name="login_form" action="" method="POST" class="form"> <label>Please, enter your login data</label> <input id="csrf_token" name="csrf_token" type="hidden" value="IjgwYTBhNWJkNTQxMDhlNjY3Mzk1MDZiYmQ1MGQ4MWI1NmQyOTVkNTMi.DYsAdQ.4G1yjSqVL3H540_slsMhCIQWm3Y">

<div class="field">
    <input id="email" name="email" placeholder="Email" type="text" value="">
</div>

<div class="field">
    <input id="password" name="password" placeholder="Password" type="password" value="">
</div>

<div class="field">
    <input id="csrf_token" name="csrf_token" placeholder="CSRF Token" type="hidden" value="IjgwYTBhNWJkNTQxMDhlNjY3Mzk1MDZiYmQ1MGQ4MWI1NmQyOTVkNTMi.DYsAdQ.4G1yjSqVL3H540_slsMhCIQWm3Y">
</div>

        <button type="submit" id="submit">Login</button>
    </form>
