Short code showing

We received short code showing instead of form values from some of senders. It works fine on us.

This is the form

<label> Name (required)
[text* your-name] </label>

<label> Email (required)
[email* your-email] </label>

<label> Mobile number
[tel* tel-318] </label>

<label> Your Message
[textarea your-message] </label>

[recaptcha]
<br>
[submit “Send”]

And this is the email message body
From: [your-name] <[your-email]>

Message Body:
[your-message]

Thank you
