So, are there any images with sharp bits in the affected areas? It is interesting that elsewhere the edge is well-defined... so it might be a software issue.

There are sharp edges, but your camera never record them. See the diagram below:

When you focus on the green object, you also record blur edges of the red object. But as you focus on the red object. Your camera no longer see the red edges. When you stack the pictures. The the red edges will be blur. There is nothing you can do unless you move both your camera and the focus ring to make sure the perspective of your camera remain the same on all pictures. That would be nearly impossible! Or use a very long lens to minimise the effect.
