Enum to Dropdown in MVC 5

I have a `nullable` `enum` defined for a person title and used in a person model. ``` public enum Titles { Mr=0, Mrs=1, Miss=2, Dr=3 } ``` ``` [Required(ErrorMessage="Please supply the title.")] [Display(Name = "Title")] public Titles Title { get; set; } ``` When I add this property into a create or edit view using the HTML Helper ``` @Html.EnumDropDownListFor(model => model.Title) ``` the control renders as expected with the enum values within it. However, when I choose to edit an existing person, the title `enum` doesn't show the current title. It shows an empty entry at the top of the `DropDownList`. However, if I remove the `nullable`, it always shows the first item in the `enum`. Any ideas how I get the `DropDownList` to display the correctly chosen `enum` item for the person I am editing? Many thanks, Jason.
