reCaptcha problem

Hi,
I’m currently having a big issue with your reCaptcha integration in CF7.
When enabling it, it won’t let anyone send any messages. Although the captcha is recognized correct, no messages will be send. I also noticed a second input field under the checkbox of the captcha part which seems to be an error as well. Since it’s from the reCaptcha shortcode I cannot remove it.
Additionally I noticed when putting a form using reCaptcha on one of my pages generated with TemplateToaster, it destroys the footer image width on this particular page.
Along with this I use autoptimize as a plugin but disabling it didn’t help me.
Is there any known fix for this to make it work again?

If you want to take a look at it, just go to https://www.makotodojo.org/find-us/ and you can see what I mean when you scroll all the way down to the bottom and the contact form.

Thanks!
