Just to be clear, this is a user forum and Cyberlink Customer Service/Tech Support doesn't typically see what's posted here.
If you filed a support ticket with Cyberlink last year to report the issue, you would have received a ticket with a CS number. If you only posted about the issue on the forum but didn't file a request, then the developers actually haven't been informed.
I have tested your steps, and I agree that the freeform shape is not properly stored in the keyframe settings. Also, if you change the existing shape at one keyframe, the shape will change at other points, and the shape there will no longer match what you originally set up. Each one affects the other.
This is clearly a bug, and I will report it. If you received a CS # last year, please post it and I will include it in my support request.
Thanks for posting that the issue is still here!
