Hi
Thanks for your remark. I have reproduced this problem. And I have logged this problem to our defect base as issue # 3393. We will try to fix it in our next release, which will be published in a couple of weeks. A notification will be posted here in this thread as soon as it will be done.
Additionally I can tell, that the custom properties you add programmatically are added to the target document, but you can see it only in file\right click menu\properties\custom.
Best regards.
