Add MultiSelect ComboBox inside PDF using C# Aspose.PDF - MultiSelect is not working

Why does Aspose.PDF ComboBoxField.MultiSelect not work??

ComboBoxField cbx = new ComboBoxField(doc, cbxSize);
cbx.DefaultAppearance.FontSize = fontSize;
cbx.DefaultAppearance.FontName = fontName;
cbx.SetPosition(pointPosition);
cbx.PartialName = partialName;
cbx.TextHorizontalAlignment = horiAlign;
cbx.Editable = editable;

        switch (fontColor)
        {
            case ColorEnum.Color.Black:
                cbx.DefaultAppearance.TextColor = System.Drawing.Color.Black;
                break;
            case ColorEnum.Color.Red:
                cbx.DefaultAppearance.TextColor = System.Drawing.Color.Red;
                break;
        }

        foreach (string item in cbxItems)
        {
            cbx.AddOption(item);
        }

        cbx.MultiSelect = multiSelectable;
        doc.Form.Add(cbx, 1);
