I think this issue came after a servicepack update

We have a scheduled report based on following:

Get members of several specific AD groups (361 groups).

The report are delivered in XLSX

When we receive the Spreadsheet, every single group are made as a new sheet inside the spreadsheet. So in this case 361 sheets

.

What we want is a single column with the AD group name so that we are able to sort the data. Now we have to look into every sheet.

I tried to do this with a CSV file, but I am not able to select the AD group name as a column 

How can I overcome this problem?

Thanks
