SUMMARY
***
While usign the blur effect as a layer or the drop shadow, it will not scale proportionally when saving with the option "advanced export"

***


STEPS TO REPRODUCE
I added a file with the first steps already done.

Blur layer:
1.  Make a 2048*2048 image
2 make a new layer and draw some shapes in it
3.  duplicate that layer and add a filter layer with gaussian blur at maximum to add a "glow"
4. click on advanced export 
5. scale at 256*256

drop shadow style:
1.  Make a 2048*2048 image
2. make a new layer and draw some shapes in it
3.  add a visible drop shadow effect, I used "normal" with max opacity and max size
4. click on advanced export 
5. scale at 256*256


OBSERVED RESULT
the product image will have a much wider "glow"

EXPECTED RESULT
the new image should be a tinier version of the one you save from, with the same look

SOFTWARE/OS VERSIONS
Windows 10

I've also come across this issue. I would expect Advanced Export to export a flattened copy.

Fix Advanced Export of the image with filter masks or layer styles

Basically, the image if flattened before export in the following cases:

1) The export format does not support layers (a general warning appears)
2) The image contains a filter mask or layer (a warning appears that the image
    is going to be flattened before export)
3) The image contains a layer style (a warning appears that the image
    is going to be flattened before export)
