Have you inputted the secret key into the corresponding webflow field? 
You can find the legacy secret key in the "Integrate with a third party" banner in your second screenshot, clicking on "Integrate with a third-party service or plugin".

This is where i put the secret key in the site settings. Did i put it on the right field?

Hi jared_04,

Thanks for reaching out. That is indeed the right place to input the site key and secret key on Webflow, according to https://help.webflow.com/hc/en-us/articles/33961418101139-Add-a-reCAPTCHA-element#how-to-add-a-recaptcha-element-to-a-form

Have you followed every step of the instructions by Webflow?

Maybe this post is helpful? https://discourse.webflow.com/t/email-from-google-recapcha-you-arent-protected/294096/7(btw, your key version is correct. maybe you can republish it?)

On our end, we see that your key is installed properly on the frontend, but lacking proper installation on the backend. I assume this is supposed to be taken care of by Webflow.
