Clear Hidden Fields: Is this a new feature?

Is this something new?  I was getting information before that is now not being sent. I just went through all my forms and changed this preference.  Hope this works.

This is not a new feature, this was there in the v3 builder and will still there in the v4 version too. 

Please, if you experience any problem with this feature or with your forms, do not hesitate to let us know, we  will be glad to help you.
