Cloudflare Captcha not enabling

Hello,

In settings, I have enabled the Cloudflare Turnstile and I have set the pair of Site/Secret Key. When I try to enable captcha in form settings, I get the following error message:

“Seems like you are trying to enable the captcha feature, but the captcha keys are empty. Please click here to add them and save your form.”

The link leads me back to the Settings page to renter the pair of keys. Any insight on what I may have missed? Any idea on how to resolve this problem? Any suggestion is more than welcome.

Thank you for your time.

Regards
