reCAPTCHA theme:dark – Not Working

For some strange reason the reCAPTCHA theme:dark shortcode is not working. I have spent hours trying to figure out what is causing the problem and even tried changing the default from Light to Dark in the Contact Form 7 php, but nothing seems to effect it.

No matter what changes I make, the code still shows as rc-anchor-light

My Form Layout:

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

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

<label> Subject
[text your-subject] </label>

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

[recaptcha theme:dark]

[submit “Send”]
