After Adding values to my profile packages and inspecting it from my JS that it has data contained in it, but on my server side when i push, ProfilePackages results to count = 0; even when Object List has Data.

This is my JS Code

var formData = new FormData();
    formData.append("Title", $("#profileTitle").val());
    formData.append("Duration", $("#txtDuration").val());
    formData.append("StartingPrice", $("#startPrice").val());
    formData.append("Description", $("#txtDescription").val());
    formData.append("CategoryId", $("#SubCatDropDown").val());
    $("#tablePackage tbody tr").each(function () {

        var packageDetails = {};
        packageDetails.Description = $(this).find("#desc").val();
        packageDetails.Amount = $(this).find("#amount").val();
        packageDetails.Duration = $(this).find("#hours").val();

        formData.append("ProfilePackages", JSON.stringify(packageDetails));
    });
   
    $.each($("#skills option:selected"), function (i, selected) {
        formData.append('ProfileSelectedSkills', selected.value);
        console.log(selected.value);
    });
    $.each($('.fileUpload')[0].files, function (key, input) {
        formData.append('Files', input);
        console.log(input);
    });

    $.ajax({
        async: true,
        type: 'POST',
        dataType: 'JSON',
        contentType: 'application/json; charset=utf-8',
        data: formData,
        processData: false,
        contentType: false,
        url: '/F/Profile/FAddProfile?handler=SaveProfile',
        beforeSend: function (xhr) {
            xhr.setRequestHeader("MY-XSRF-TOKEN",
                $('input:hidden[name="__RequestVerificationToken"]').val());
        },
        success: function (data) {
            alert(data);
            window.location = '/F/Profile/FProfile'; // redirect
        },
        error: function () {
            alert("Something went wrong");
        }
    });

And this is my Controler Model

 public int Id { get; set; }
    public string Description { get; set; }
    public int CategoryId { get; set; }
    public decimal StartingPrice { get; set; }
    public int Duration { get; set; }
    public string Title { get; set; }
    
    public virtual List<ProfileSkill> ProfileSkills { get; set; } = new List<ProfileSkill>();
    public virtual List<ProfileFiles> ProfileFiles { get; set; } = new List<ProfileFiles>();
    public virtual List<ProfilePackage> ProfilePackages { get; set; } = new List<ProfilePackage>();

When i push, ProfilePackges result to count = 0
