Spreadsheet with track changes and pivot tables

Hi.
I have a problem that i am unable to solve.
I have a spreadsheet with several sheets in it, one sheet is a standard
data 
sheet with text and numbers and the rest of the sheets are pivot tables.
My problem is that i want to enable the feature Track Changes on the sheet

with the text and number data, but when i do this the rest of the sheets
that 
are pivot tables gets disabled. When i enable the track changes feature in

the spreadsheet i get a question about saving the spreadsheet as a shared 
workbook, when i choose yes here all the pivot tables gets disabled.
So, is there any way to have a spreadsheet with several sheets that are 
pivot tables and one sheet with data in it to have track changes enabled
on 
it? (The sheet that i want to enable track changes on is not a pivot
table)

Sincerely
Henrik Andresen
