mailchimp for wp display issue last text input box

Hello,

My last text input box of three is more narrow than the others. The hint type inside the box is also smaller.

I’m using WordPress version 3.8.1 and I updated the MailChimp for WP plugin this morning. Still no success.

Here’s my code:

<p>
	<label for="mc4wp_name">Name: </label>
	<input type="text" id="mc4wp_name" name="NAME" required placeholder="Your name" />
</p>

<p>
	<label for="mc4wp_company">Company: </label>
	<input type="text" id="mc4wp_company" name="COMPANY" required placeholder="Your company" />
</p>

<p>
	<label for="mc4wp_email">Email address: </label>
	<input type="email" id="mc4wp_email" name="EMAIL" required placeholder="Your email address" />
</p>

<p>
	<input type="submit" value="Sign up" />
</p>

Here’s a link to the screenshot:

Any help would be appreciated.
Thanks,
Beth
