So it looks like the issue does not occur if you are using rules to ‘hide’ the input fields (rather than using rules to ‘show’ the fields). Therefore I just need to reverse engineer all the rules to not show when the DOB is in the wrong range.
Would be great if the bug could be looked at though because it makes my rules more complex and it would be nice for it to be as simple as possible.
Thanks for such an awesome form builder!
