Wrong form when disconnected

Hello !

I created this form, which displays fine when I’m connected to the site :

<p>
    <input type="text" name="FNAME" required="" placeholder="Prénom">
</p>
<p>
	<input type="email" id="email" name="EMAIL" placeholder="E-mail" required>
</p>
<p>
	<input class="submit" type="submit" value="Abonnez-vous">
</p>

But when disconnected, the code appears like this :

<p>
    <label>Prénom</label>
    <input type="text" name="FNAME" required="" placeholder="Prénom">
</p>
<p>
    <label for="email">
        Adresse de courrier électronique: 
	<input type="email" id="email" name="EMAIL" placeholder="E-mail" required>
    </label>
</p>
<p>
	<input class="submit" type="submit" value="Abonnez-vous">
</p>

I cannot juste hide labels because i got one input inside of it. How come it behaves like this ?
