Hello Kristina,
can you try the attached patch to org.apache.pdfbox.multipdf.Splitter?
It should copy the PDF version of the source to the newly created documents.
Note that PDFBox always sets the version in the header to 1.4 and this
only updates the /Version entry in the Document Catalog. This should
be enough (at least it works with Adobe Reader).
Best
Martin
