Why are replies being marked as Spam

Hi,

We’re using Invisible Captcha on a test environment with a view to pushing it on the live environment. We use a number of Gravity Forms on the site including a registration form.

When the form is completed all the entries seem to be marked as SPAM by this plugin so none of the data is moved to the right places post submission of the form.

What’s happening here to make this happen? I was using an outlook email address and I’m worried with the variety of names and email addresses, that we push this all live and we lose registrations as a result.

Any help would be appreciated to understand this all.
