When using PDFMergerUtility to merge the attached PDF twice into one document there may be data missing.
To be more specific: In this case the data on page 1 looks fine, but page 28 is empty. My expectation is that page 28 is identical to page 1 (the document has 27 pages).
Of course that's not a common use case. But I can reproduce this behaviour with other documents which are not identical, but similar.
What is the trigger for this and is there a workaround?
