Commented Unassigned: Pivot Tables Values Problem [9088]

Based on the example [Pivot Tables](https://closedxml.codeplex.com/wikipage?title=Pivot%20Table%20example) , do the following steps to reproduce the problem

Excellent example . It works perfect, but if you add more than one value will have a problem . Here I leave an example to reproduce the problem . Suppose Pastry class has one more property called "Amount" int

Step 1. Add two values

```
// The values ​​in our table will come from the " NumberOfOrders " field
// The default setting is a full calculation of each row / column
pt.Values.Add ("NumberOfOrders");

// Another value ( THIS IS THE ONE THAT CAUSE THE PROBLEM )
pt.Values.Add ("Amount" ) ;

```


Step 2. Save the excel file

Step 3. Open the excel file , and throw the following message

We found a problem with Content ' Patry.xlsx ' . Do you want to try to recover as much content as possible ? If trusts origin of this book , please click yes .

Hi, I have the same problem. I performed the following test:
1. creating an excel file (A.xlsx) with a pivot with only one Values using ClosedXML;
2. opening the created excel file;
3. adding another Value to the pivot and save it;
4. creating an excel file (B.xlsx) with the same Values using ClosedXML;
After that:
5. I renamed A.xlsx and B.xlsx to A.zip and B.zip
6. I unzipped then I used DiffMerge to compare them:
6a. in A.xlsx there are data related to pivot table values written into the sheet which contains the pivot table itself.
6b. in B.xlsx the sheet which contains the pivot table hasn't that data.
