SetSheetPrOptions error

[Jeltopuz]

f, err := excelize.OpenFile(filename)
	if err != nil {
		log.Fatal(err)
	}
if err := f.SetSheetPrOptions(sheet,
			excelize.OutlineSummaryBelow(false),
		); err != nil {
			panic(err)
		}

	err = f.SaveAs(filename)
	if err != nil {
		log.Fatal(err)
	}

If file is NewFile - it works
If file if OpenFile and file is empty - it works
If file is not empty - i get error:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"><logFileName>error122560_01.xml</logFileName><summary>Обнаружены ошибки в файле "C:\Users\a.kuimova\planningOfWorkDurations\app\filename.xlsx"</summary><removedParts><removedPart>Замененный компонент: часть /xl/worksheets/sheet1.xml с ошибкой XML.

Hi @Jeltopuz, thanks for your issue. I have fixed it. Please try to upgrade the library with the master branch code.
