Validation Exception on select list of entities that have already been validated

Question

I'm using a ViewModel to combine two entities in one view. for the first entity im using textboxfor & lablefor html helpers to gather data for a post request. For the second entity Im using a dropdownlistfor which is a selectlist of a group of address objects which are entered in another view. i have used data annotations on my address class to make all fields required. once entries have passed validation and saved to my database via the add address view. when i try to select it with a view model i get validation exception indicating that the fields are required on my address entries

if i remove validation on the address class it seems to work

my controller

public ActionResult AddMember()
    {
        var ViewMember = new MemberViewModel(); 
            ViewMember.AddressList = new SelectList(_context.Addresses, "Id", "streetName");



        return View(ViewMember);
    }




    [HttpPost]
    public ActionResult AddMember(MemberViewModel Entry)
    {
        var entry = new Member();
        entry = Entry.member;

        entry.Address = new Address() {Id= Entry.addressId };

        if (ModelState.IsValid)
        {

            repository.AddMember(entry, _context);

            TempData["message"] = "Your Member was added";


            return RedirectToAction("Members", new { id = entry.Id });
        }
        return View();
    }

my view

@model  AdesinaWebApp.ViewModels.MemberViewModel
@{
  ViewBag.Title = "AddMember";
  Layout = "~/Views/Shared/_Layout.cshtml";
}

 <h2>AddMember</h2>

@using (Html.BeginForm()){


@Html.LabelFor(fn => fn.member.Name)<br>
@Html.TextBoxFor(fn => fn.member.Name)<br /><br />

@Html.LabelFor(fn => fn.member.LastName)<br>
@Html.TextBoxFor(fn => fn.member.LastName)<br />

@*@Html.LabelFor(fn => fn.address.DoorNumber)<br>
@Html.TextBoxFor(fn => fn.address.DoorNumber)<br /><br />

@Html.LabelFor(fn => fn.address.streetName)<br>
@Html.TextBoxFor(fn => fn.address.streetName)<br /><br />

@Html.LabelFor(fn => fn.address.PostCode)<br>
@Html.TextBoxFor(fn => fn.address.PostCode)<br /><br />*@



@Html.LabelFor(m=>m.addressId)
@Html.DropDownListFor(m=>m.addressId,Model.AddressList,"please select your address")



<button type="submit">Submit</button>

 }

my view model

 public class MemberViewModel


{

    public int addressId { get; set; }

    public Address address { get; set; }

    public Member member { get; set; } = new Member();

   public SelectList AddressList { get; set; }



}

my address class

public class Address
{
    [Key]
    public int Id { get; set; }
    [Required(ErrorMessage = "Please enter a Door Number")]
    public int DoorNumber { get; set; }
    [Required(ErrorMessage = "Please enter a Street Name.")]
    public string streetName { get; set; }
    [Required(ErrorMessage = "Please enter a Post Code.")]
    public string PostCode { get; set; }

    public ICollection<Member> Members { get; set; }
}

your help will be much appreciated
