Incorrect formula value after calling Worksheet.CalculateFormula


After calling Worksheet.CalculateFormula the value of a formula is changed and wrong.
For reproducing the issue please use the attached XLSX file and the following code:

var excelDocument = new Workbook(“PivotFormula.xlsx”);
var worksheet = excelDocument.Worksheets[0];
var value = worksheet.Cells[“J5”].DisplayStringValue;
Console.WriteLine(“Before Worksheet.CalculateFormula: {0}”, value);

worksheet.CalculateFormula(true, false, null);

value = worksheet.Cells[“J5”].DisplayStringValue;
Console.WriteLine(“After Worksheet.CalculateFormula: {0}”, value);
