HI @paulcityhopper – it shouldn’t be setting every hidden field, just the Honeypot hidden field. If it is modifying other fields in your form, please do let me know, as that is unusual behaviour indeed.

As for the “nope” value, pleas refer to this post (sticky in the support form, so it isn’t missed 😉 ), for a detailed explanation and workarounds: https://wordpress.org/support/topic/w3c-validation-in-1-11-explanation-and-work-arounds/
