FitText in WordDocument do not refresh

Hello,

i add a Table to new word document. then i modify the cell with "TextWarp" and "FitText" but afte opend the word document the text in cells arent fitted.

When i focus the row the text fits.

Is there any problem?

My code:

foreach (XmlTemplate.TableRow tableRow in xmlTemplate.TableRows)
{
if (tableRow.Type.CompareTo("Header") == 0)
{

Debug.WriteLine("Add ROW");
WTableRow row = wTable.AddRow();
row.Height = GetCmToFloat(Convert.ToDecimal(0.875));
row.IsHeader = true;
row.HeightType = TableRowHeightType.Exactly;
foreach (XmlTemplate.Cell cell in tableRow.CellsList)
{
WTableCell wTableCell = row.AddCell();
wTableCell.Width = GetCmToFloat(cell.Width);

IWTextRange wTextRange = wTableCell.AddParagraph().AppendText(cell.Text);

wTextRange.CharacterFormat.FontName = string.IsNullOrEmpty(cell.Font) ? "Arial" : cell.Font;
wTextRange.CharacterFormat.FontSize = cell.FontSize;
wTextRange.CharacterFormat.Bold = true;
if (!string.IsNullOrWhiteSpace(cell.Halignment))
{
wTextRange.OwnerParagraph.ParagraphFormat.HorizontalAlignment = HorizontalAlignment.Center;
}
}
}
}

....

IWSection wSection = wordDocument.Sections[0];
IWTable wTable = wSection.Tables[0];
for (int i = 0; i <= wTable.Rows.Count - 1; i++)
{
WTableRow row = wTable.Rows[i];
List cellList = xmlTemplate.TableRows[i].CellsList;
for (int j = 0; j <= row.Cells.Count - 1; j++)
{
XmlTemplate.Cell cell = cellList[j];
WTableCell wTableCell = row.Cells[j];
wTableCell.CellFormat.SamePaddingsAsTable = false;
wTableCell.Width = GetCmToFloat(cell.Width);
if (cell.CellMargin != null)
{

wTableCell.CellFormat.Paddings.Left = GetCmToFloat(cell.CellMargin.Left);
wTableCell.CellFormat.Paddings.Right = GetCmToFloat(cell.CellMargin.Right);

}
else
{

wTableCell.CellFormat.Paddings.Left = GetCmToFloat(Convert.ToDecimal(0.1));

}
wTableCell.CellFormat.TextWrap = cell.IsTextWarp;
wTableCell.CellFormat.FitText = cell.IsTextWarp;

wTableCell.CellFormat.Borders.BorderType = BorderStyle.Single;
wTableCell.CellFormat.Borders.LineWidth = 1;
wTableCell.CellFormat.VerticalAlignment = VerticalAlignment.Middle;
wTableCell.CellFormat.HorizontalMerge = CellMerge.Start;
wTableCell.CellFormat.BackColor = Color.LightGray;

}
}
