Export out to swf blur/transparency problems.

I was wondering if anyone exported/import in flash cc2014/2015.

Basically i exported out a test of an animation.

Using the box blur the results were:
The tween worked fine, but no blur was shown running the swf in flash player.

Import the swf into a flash project also had no blur.

Using transperancy:
The tween worked fine, transparency seemed to work while running the swf in flash player

Importing the swf into a flash project broke the transparency, so that at the end of the animation it stayed completely visible.

Open to ideas!
