Why doesn't it show Country Picker?

I try put in country picker in my form and every time I try go on the form and fill it it doesn't show the country droplist? Is there a reason for this? 

Hi there,

I've cloned your form and when I checked the Country field, I saw that it was just a textbox. Have you tried our Country Picker widget? I think its just what you're looking for. You can easily add a country picker field to your form in our form builder:

If you need further assistance please let us know.
