New Post: Small problem NPOI + Excel 2010. buttons switched.

Hello,

I have a small and somewhat peculiar problem,
when I generate an .xls file from an xml source with HSSFWorkbook

and I open this file in excel 2010(compatibility mode) , the buttons for Financial notation and Thousands notation are switched around.

I am using NPOI 2.1.1 from the codeplex download page (not github or nuget)

The problem is not there when I open the file in excel 2003 or libreoffice calc.
when I convert to .xlsx within excel 2010 the problem also disappears.

Is this a problem of Excel 2010(compatibility mode) or of NPOI?
I tried googling this problem in terms of excel 2010(compatibility mode) but I did not find an answer.

I know this is a minor issue but thanks in advance anyway.
