ClosedXML and PageBreaks format

Hello,

 

I have 5 Excel files with pagebreaks format, but when I write in these files with ClosedXML and C#, the pagebreaks format disappears and the normal format appears. Nevertheless, when I open the files and I go to Display option then PageBreak, it returns to the right format (PageBreak format).

In fact, I would like that after writing in Excel files with ClosedXML, the PageBreak format remains (PAgeBreak format). 

 

Do you know how to keep pagebreaks format in these files after writing in these files with ClosedXML, please?

 

Thanks.
