reCAPTCHA verification failed – Reset password

My v3 reCAPTCHA plugin is working fine bar on the Reset Password page.
So for the “wp-login.php” page, I have no issues but when a user has lost their password and requests a reset, they get their email OK and click on the link however the page “wp-login.php?action=rp&wp_lang=en_GB” always comes up with the error –

ERROR: reCAPTCHA verification failed.

Please try again.

Any help for this would be much appreciated.

I have already looked through the forum and there are verification failed posts but none of them seem to relate to my issue.
