Trouble with updating runs in header table with data

[peterykt]

I think i find bug with getting table data in header
in class XWPFHeader
method
OnDocumentRead
when reading
headerFooter.Items
it should be

foreach (object o in headerFooter.Items)
                {
                    if (o is CT_SdtBlock)
                    {
                        foreach (object oo in ((CT_SdtBlock) o).sdtContent.Items)
                        {
                            if (oo is CT_P)
                            {
                                XWPFParagraph p = new XWPFParagraph((CT_P) oo, this);
                                paragraphs.Add(p);
                                bodyElements.Add(p);
                            }
                            if (oo is CT_Tbl)
                            {
                                XWPFTable t = new XWPFTable((CT_Tbl) oo, this);
                                tables.Add(t);
                                bodyElements.Add(t);
                            }
                            if (oo is CT_SdtBlock)
                            {
                                XWPFSDT c = new XWPFSDT((CT_SdtBlock) oo, this);
                                bodyElements.Add(c);
                            }
                        }
                    }
                }
            }

because it has CT_StdBlock
But i still has a bug - it create multiple headers (3 times) with one replaced header
