I tried splitting a document crated by LibreOffice Writer. The first page looks fine, but all other pages are completely empty when displaying them.

I used pdfcpu commit 8c35cdc
Compiled with go 1.17 on Ubuntu 21.04
executed command: pdfcpu split three_pages.pdf .

Here is a very simple pdf to reproduce the issue: three_pages.pdf

Validation shows the following results:
Original pdf:

validating(mode=relaxed) three_pages.pdf ...
validation ok

First splitted page:

validating(mode=relaxed) three_pages_1.pdf ...
validation ok

Second page:

validating(mode=relaxed) three_pages_2.pdf ...
validation error (obj#:3): pdfcpu: dereferenceDict: wrong type pdfcpu.StreamDict <<<
<Filter, FlateDecode>
<Length, (4 0 R)>

Third page:

validating(mode=relaxed) three_pages_3.pdf ...
validation error (obj#:3): pdfcpu: dereferenceDict: wrong type pdfcpu.Integer <137>

Full validation report for page 2:

pdfcpu validate -vv three_pages_2.pdf
validating(mode=relaxed) three_pages_2.pdf ...
