Contact Form 7 Doesn’t Work

I set up a custom form that has multiple forms but when i tested it and clicked “Submit” i got this strange lightbox effect with a blank white square. What’s going on?

This is my code:

<p>Name #1 (required)<br />
    [text* your-name] </p>

<p>LinkedIn (required)<br />
    [text* linkedin-1]</p>

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

<p>Phone Number<br />
    [text phonenumber]</p>

<p>Address<br />
    [text address1]</p>

<p>Company<br />
    [text company1]</p>

<p>Title<br />
    [text title1]</p>

<p>Name #2 (required)<br />
    [text* your-name-2] </p>

<p>LinkedIn (required)<br />
    [text* linkedin-2]</p>

<p>Your Email (required)<br />
    [email* your-email-2] </p>

<p>Phone Number<br />
    [text phonenumber-2]</p>
