On the other hand, most of my stacked images of flowers are against black backgrounds, and that may be an important difference, depending on how the software works.
Have you tried stacking this set with another software program to see if the problem replicates? If you don't have other stacking software, I would be happy to try it in Zerene, if you want to put the raw files in a dropbox or other cloud location.
