Help! Publish to PDF, but subject in PDF stays empty

Help! My problem when I punish from Coreldraw to pdf is that the pdf properties show the keywords of the cdr file, but not the subject. Doesn't work in manual publish to pdf nor in macro:

With ActiveDocument.PDFSettings
.Subject = "These words don't show up in the pdf"
End with

Another strange thing: if I publish to pdf a .cdr file and then open the pdf in Acrobat and check the properties, the title shows the original .cdr extension. Through Acrobat Reader and Chrome browser this title with .cdr also ends up as the title of the Tab or browser Window. I don't want people so see how I make pdf's!
For instance Google "GBM_17-1274.pdf"

This has been bothering me for years. I hope someone has a solution and can help me.
