[Forminator Pro] {all_fields} in user email

I want user to keep a record about what they input in the form.
In "edit form" > "to admin(s)" I saw: {all_fields}, so i copied {all_fields} in textarea of "to user".
When user got the mail, it didn't show all fields as admin, but only shows the shortcode: {all_fields}.
How can i make all user get the mail with all fields?
