PDF file missing part of grey hatch

Hello all,

I created a batch printing script for Revit.
I am running into an error with the PDF Files.

There is a part on the PDF that does not get filled in with a grey hatch.

Below a small snippet of the PDF file

And below what its supposed to look like:

I have tried printing with another PDF printer and that works fine so this is a PDFCreator issue. Can anyone help me out?

This only happens when i use a very large papersize (A0++), if i change the size to A0 it works fine without loss of color.
