Unable to see the stacks changes in Prototype mode

Hi All, 

I am creating a form design in XD, Some fields are dependent based on their parent field inputs so I am using stacks feature in that case. Attached is the video where stacks work perfectly fine XD file but spacing changes does not affect in prototype mode.

Kindly check the video for better understanding, if someone can suggest any solution/work around, that would be helpful.

Thanks.
