Empty Data in mail

Hi,

Your plugin is great but I’m facing a problem.

Step 1 :

<p>Your Name (required)<br />
    [text* your-name] </p>

<p>Your Email (required)<br />
    [email* your-email] </p>

<p>Subject<br />
    [text your-subject] </p>

<p>Your Message<br />
    [textarea your-message] </p>

<p>[submit "入力内容を確認する"]</p>
[multistep "1-2-http://url/engagement-entry-form"]

Step 2 :

<p>Your Name (required)<br />
    [multiform your-name] </p>
<p>Your Email (required)<br />
    [multiform your-email] </p>
<p>Subject<br />
    [multiform your-subject] </p>
<p>Your Message<br />
    [multiform your-message] </p>
<p>[submit "Send"]</p>
[multistep "2-2"]

Mail Tab (Step 2 form)

From: [your-name] <[your-email]>
Subject: [your-subject]

Message Body:
[your-message]

But here is the mail I receive :

From: <>
Subject: 

Message Body:

Any ideas where the problem could come ? I can provide url if needed
