When document with TOC  field is exported to PDF, the hyperlinks in the TOC field are exported with blue fore color and blue underline (with the default hyperlink styling). Instead, they should be exported with the fore color visible in the document.

Workaround: Clear the hyperlink style from the spans inside the TOC:

var firstTocRange = this.radRichTextBox.Document.EnumerateChildrenOfType<FieldRangeStart>().Where(frs => frs.Field is TableOfContentsField).First();
this.radRichTextBox.Document.Selection.SelectAnnotationRange(firstTocRange);
foreach (var spanLayoutBox in this.radRichTextBox.Document.Selection.GetSelectedBoxes<SpanLayoutBox>())
{
	spanLayoutBox.AssociatedSpan.Style = null;
}
