I'm having an issue with iText when generating PDF from HTML. I'm passing the "import information section" from Locize, which contains bold tags and list bullet
<li>\n
<b>Toll-free</b> (within Canada and the USA):
<b>1.800.xxxxxxx</b>\n
</li>\n
The pdf file is generated in Confirmation.cs. The parameter "medSrc" passing from Confirmation.cs to ImportantInformation.cs is listed below. Somehow, the bold style and the list bullets just don't apply to the outcome pdf file.
I have been debugging this for a while and still no clue about what's going on. Does anyone know what I missed?
Thank you in advance!

The medSrc:

Updates: Here is the definition for the functions of ElementToCell and HtmlToElements
public static class HtmlToCellFormat
{
public static string baseUri = "/";
public static void ElementToCell(this Cell cell, IElement e)
{
var type = e.GetType().ToString();
if (e.GetType() == typeof(Image))
{
cell.Add((Image)e);
}
else if (e.GetType() == typeof(Paragraph) || (e.GetType() == typeof(List)))
{
cell.Add((IBlockElement)e);
}
}
public static IList<IElement> HtmlToElements(string content)
{
ConverterProperties properties = new ConverterProperties();
properties.SetBaseUri(baseUri);
FontProvider fontProvider = new DefaultFontProvider(false, false, false);
FontProgram fontProgram = FontProgramFactory.CreateFont();
fontProvider.AddFont(fontProgram, "");
properties.SetFontProvider(fontProvider);
IList<IElement> elements = HtmlConverter.ConvertToElements(content, properties);
return elements;
