Recaptcha after "Sent" Button how to solve it?

[Ehnoah]

So when I try to register on a Form, it randomly gives you a re-captcha when you press sent.

I marked this Captcha that pops up as Captcha and CapCloud recognizes it and response with an Answer (like F2) but he doesn't click anything, or I am sure that only one image is correct.

So curious how I solve such Re-Captchas that appear after clicking the sent Button?
