Error binding not-null value in DropDownList

Getting "Cannot read property 'isComplexArray' of null" when binded property is initialized on render (se example below). If "SelectedGame" is not initialized, no error is thrown. I'm on latest Blazor

3.2.0-preview1.20073.1, latest dotnet 3.1.2  and latest Syncfusion  17.4.0.51



<EjsDropDownList TValue="string" TItem="Games" Placeholder="Select a game"  @bind-Value="@SelectedGame" DataSource="@LocalData">

<DropDownListFieldSettings Value="ID" Text="Text"></DropDownListFieldSettings>

</EjsDropDownList>


    string SelectedGame { get; set; } = "Game4";

    public class Games

    {

        public string ID { get; set; }

        public string Text { get; set; }

    }

    List LocalData = new List {

    new Games() { ID= "Game1", Text= "American Football" },

    new Games() { ID= "Game2", Text= "Badminton" },

    new Games() { ID= "Game3", Text= "Basketball" },

    new Games() { ID= "Game4", Text= "Cricket" },

    new Games() { ID= "Game5", Text= "Football" },

    new Games() { ID= "Game6", Text= "Golf" },
