Receiving blank form submissions

I am receiving blank forms even though I've set required fields.

I checked your form and I can see that only the Captcha field is required. I cloned your form and I was able to submit it just by filling up the Captcha field. I recommend you set 1 or 2 more fields as required.

Is this form embedded on a webpage? If yes, then please provide the URL so that we can further investigate.

Thank you.
