Syncfusion Blazor Grid not loading correctly

Hello,

Im trying to create a project using Syncfusion.Blazror.Grid NuGet package (20.3.0.49). I have created a simple table that should be displayed in gridcolumns. 

@page "/"

@using TheContactList.Shared

@using Syncfusion.Blazor.Grids

<SfGrid DataSource="@Contacts">

    <GridColumns>

        <GridColumn Field=@nameof(Contact.ContactId) HeaderText="ID"></GridColumn>

        <GridColumn Field=@nameof(Contact.FirstName) HeaderText="Imię"></GridColumn>

        <GridColumn Field=@nameof(Contact.LastName) HeaderText="Nazwisko"></GridColumn>

        <GridColumn Field=@nameof(Contact.Email) HeaderText="Email"></GridColumn>

    </GridColumns>

</SfGrid>




@code{

    public List<Contact> Contacts { get; set; }


    protected override void OnInitialized()

    {

        Contacts = LoadData();

    }


    private List<Contact> LoadData()

    {

        //Dodaje paru pracowników w ramach testu

        Contact c1 = new Contact

            {

                ContactId = 1,

                FirstName = "Anna",

                LastName = "Nowak",

                Email = "anowak@gmail.com",

                Password = "sfsfgg",

                DateOfBirth = new DateTime(2003, 07, 10),

                CategoryType = 1, 

                PhotoPath = "images/anna.png",

                PhoneNumber = 546645123




            };

        Contact c2 = new Contact

            {

                ContactId = 2,

                FirstName = "Adrian",

                LastName = "Rutkowski",

                Email = "aRutkowski@gmail.com",

                Password="wefwef",

                DateOfBirth = new DateTime(2001, 10, 18),

                CategoryType = 2,

                PhotoPath = "images/adi.png",

                PhoneNumber = 32245671


            };

        Contact c3 = new Contact

            {

                ContactId = 3,

                FirstName = "Mikołaj",

                LastName = "Cegła",

                Email = "mCegla@gmail.com",

                DateOfBirth = new DateTime(2003, 07, 10),

                CategoryType = 1,

                PhotoPath = "images/mickey.png",

                PhoneNumber = 566788111


            };

        return new List<Contact> { c1, c2, c3 };

    }

}

However when i fire up the project it displays like this:



As you can see the GridColumn has failed to load. I already tried installing the full Sf Blazor package and added

<link rel='nofollow' href="_content/Syncfusion.Blazor.Themes/bootstrap4.css" rel="stylesheet" /> to wwwroot/index.html. What else can i do to solve this problem?
