the header in the report isn't same as in the book for the same report

Summary:

NR conditional formatting/replace text isn't working for the book. as an individual report it works but when a book is ran the report header shows the system member alias instead of the conditional formatting. how can this be fixed? the weird thing is that out of many reports it's only one report that's not working. all others using the same setup works fine.
