You are facing this issue because you are removing the child nodes of content control of type Cell. Please use the following modified code to fix this issue.

private static void updateRichText(Document doc, StructuredDocumentTag sdt, String txtVal) {

    Run run = new Run(doc);
    run.setText(txtVal);

    if( sdt.getLevel() == MarkupLevel.INLINE)
    {
        sdt.removeAllChildren();
        sdt.getChildNodes().add(run);
    }
    else if( sdt.getLevel() == MarkupLevel.BLOCK)
    {
        sdt.removeAllChildren();
        Paragraph para = (Paragraph) sdt.appendChild(new Paragraph(doc));
        para.getRuns().add(run);
        sdt.getChildNodes().add(para);
    }
    else if( sdt.getLevel() == MarkupLevel.CELL)
    {
        if(sdt.getFirstChild().getNodeType() == NodeType.CELL)
        {
            Cell cell = (Cell)sdt.getFirstChild();
            cell.removeAllChildren();
            cell.ensureMinimum();
            Paragraph para = ((Cell)sdt.getFirstChild()).getFirstParagraph();
            para.getRuns().add(run);
        }
    }
}
