[Telerik Reporting] Export to CSV: First column becomes row values

I am creating a dynamic report based on a report template and the fields selected. When I export to csv, the first column has repeating data (of the first column).

Here's my web.config settings:
<configSections>
    <section name="Telerik.Reporting" type="Telerik.Reporting.Processing.Config.ReportingConfigurationSection, Telerik.Reporting, Version=7.0.13.426, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" allowLocation="true" allowDefinition="Everywhere"/>
  </configSections>

  <Telerik.Reporting>
    <Extensions>
      <Render>
        <Extension name="CSV">
          <Parameters>
            <Parameter name="NoHeader" value="false"/>
            <Parameter name="NoStaticText" value="true"/>
          </Parameters>
        </Extension>
      </Render>
    </Extensions>
  </Telerik.Reporting>

in the ReportTemplate.cs: private void table1_ItemDataBinding(object sender, EventArgs e)
        {
... //for loop - iterate all selected fields
   var textBox = new Telerik.Reporting.TextBox();
                            textBox.Name = colHeader;
                            textBox.Size = new SizeU(Unit.Inch(width), Unit.Inch(0.3));
                            textBox.CanGrow = true;
                            textBox.StyleName = "Data";
                            textBox.Value = "=Fields.[" + strColumn + "]";
...
         }

I don't experience this issue in static reports, I have placed this workaround inside the constructor:
       
       public Contracts()
        {
            InitializeComponent();

            this.textBox8.Name = "Contract Number";
            this.textBox9.Name = "Date Contract Received";
            this.textBox10.Name = "Deadline Date";
            this.textBox11.Name = "Date of Original Contract";
            this.textBox12.Name = "Contract Execution Date";
            this.textBox13.Name = "Contract Effective Date";
            this.textBox14.Name = "Contract Expiration Date";
            //this.table1.ItemDataBinding += new EventHandler(table1_ItemDataBinding);
        }

Here's the output:

Found out that what's causing exported CSV's first column to become row values was the obsolete NavigateToReportAction.Parameters for sorting. 

I commented that part and voila, that solved the problem.
