Corrupt records from OpenXML Spreadsheet creation - openxml

Question

I'm trying to generate a simple XLSX file using OpenXML but I'm getting an error when I open my file and the only info in the repairedRecord part of the log file is this:
Repaired Records: Cell information from /xl/worksheets/sheet1.xml part
The strange thing is that all the cells I'm trying to write do have the value I expect them to have. I'm just trying to write a single header row right now, where the headers is just an IEnumerable<string>:
using (var doc = SpreadsheetDocument.Create(filename, SpreadsheetDocumentType.Workbook)) {
var workbookPart = doc.AddWorkbookPart();
workbookPart.Workbook = new Workbook();
var worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet();
var sheets = workbookPart.Workbook.AppendChild(new Sheets());
var sheet = new Sheet {
Id = workbookPart.GetIdOfPart(worksheetPart),
SheetId = 1,
Name = "Sheet 1"
};
sheets.Append(sheet);
workbookPart.Workbook.Save();
var sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());
var row = new Row { RowIndex = 1 };
var column = 1;
foreach (var header in headers)
row.AppendChild(new Cell {
CellReference = GetColumnLetter(column++) + "1",
DataType = CellValues.SharedString,
CellValue = new CellValue(header)
});
sheetData.Append(row);
workbookPart.Workbook.Save();
}

If you're inserting a string value, you should be using CellValues.InlineString
foreach (var header in headers)
row.AppendChild(new Cell (new InlineString(new Text(header))) {
CellReference = GetColumnLetter(column++) + "1",
DataType = CellValues.InlineString
});
