recaptcha button is hidding

Hi.

I use plugin, set secret key and site key in label, add code to header.php, but when I set captcha button in form field, recaptha is not visible…

So, I’v been instal plugin recaptcha by Bestwebsoft. Now when I add shortcode from this plugin to content of form page, I have recaptcha button in two places: form and under form (where I add shordcode). When I delete Bestwebsoft shordcode, recaptcha is hidding everywhere -in form too…

Can you help me with it? regards
