captcha integration

Time passes and Contact Form 7 remains unbeatable, the only thing is that there is some difficulty in entering captcha, it only works with a certain integration in V2.
It appears on the Contact page, but for some reason it disappears and comes back on the Home page, even using the same shortcode. https://webbypropaganda.com.br.

Does this kind of problem occur with more people also in captcha integration?
