Two major bugs regarding printing

Cubase 8.5:
1.File sizes are huge when I make a pdf of a score. I saved a score in 6.5. Size: 1,7 MB. Same file in 8.5: 56,5 MB. This is a major problem for me, as I communicate with the outside world with pdf’s of my score/parts. Any solution??
2.Paper size (and paper orientation etc.) are not memorized when you reopen a project. My scores are made in A3 format, but reopens in A4. This bug is also new compared to 6.5, where it worked flawlessly.
Any help would be greatly appreciated - especially from Steinberg!
