Validation Message Issue

Where can we see the website in question?

Is that in my local system, so can’t share. I have checked this doc too I can see the validation works when clicking the radio button. https://contactform7.com/checkboxes-radio-buttons-and-menus/#demo
Also for check box also the same issue. when selecting a value from the check box it automatically validates the above fields. please check that demo.

Kindly please check it. How we can remove this functionality?

Thanks ??
