detail extractor issue

This new version is fascinating. But why is there some yellow border on clouds? I can recover it with some U points, but it is heavy.

Could it be due to chromatic aberration? One of my lenses was producing slight halos around objects in water or sky that would become quite exaggerated after certain kinds of editing affecting microcontrast (ClearView especially). CA correction only neutralized the color cast of the halo - but it was still there. The problem was evaluated by DxO and explained as caused by CA. I verified it for myself and found there was nothing I could do to prevent the problem with that lens.
