Transparency / Opacity is not exported correctly to png nor After Effects

Whew this has been a head scratcher! 

If I have items with transparent fills, or images imported and opacity set lower than 100% the resulting exported PNG shows it with 100% opacity. 

To be clear, I'm working with art boards with a fill set to black. Also happens if I create a black rectangle as a background. 

If I export to After effects, it looks fine, UNLESS I create a black background. Then every element that was semi transparent looks twice as transparent as in XD.

It's a real mess. 

If I place a black rectangle behind everything in XD, everything looks great. BUT - If I export to AE, all opacities jump up. With thousands of elements (I do FUI design) - this is a daunting task to fix. 

Haven't been able to find similar issues on forums etc. so I hope it's just a recent bug. Let me know how to fix. 

Thanks!

PS - one fix has been if I group an image and set the GROUP's opacity to say 20%, it will export at 20%. But if I don't have it grouped and set the image's opacity to 20%, it exports the image as 100% opaque. Halp!
