Are you referring to the Auto Fill setting?
I cloned your form and tested the Auto fill feature and it is working fine.
Please note that Auto Fill feature will only work if you access the form in the same computer and browser because the data are save in the browser cache. Another way to have a Save and Continue later feature in your form is to use the session method. You can check this article for more information: How to Save Forms to Continue Later.
