Winform Telerik RadListView populates data but text is not visible

Hello, I have the following code at the bottom which should load data automatically into the RadListView at form load. However, the text is not visible in the RadListView. I can see the exact number of rows being returned from the SQL database into the RadListView. why is the text not visible?

Thank you for your help in advance! :)

private void MemberUC_Load(object sender, EventArgs e)
        {
            //fill main panel
            this.Dock = DockStyle.Fill;
           
            using (SqlConnection con = new SqlConnection(*connection string string goes here*))
            {
                con.Open();
                cmd = new SqlCommand("SELECT FirstName, MiddleName, LastName, MemberType FROM dbo.MemberInformation");
                cmd.Connection = con;
                dr = cmd.ExecuteReader();
                while (dr.Read())
                {
                    ListViewItem item = new ListViewItem();
                    item.SubItems.Add(dr["FirstName"].ToString());
                    item.SubItems.Add(dr["MiddleName"].ToString());
                    item.SubItems.Add(dr["LastName"].ToString());
                    item.SubItems.Add(dr["MemberType"].ToString());
                    memberDetailsLV.Items.Add(item);
                }
            }
        }
