I really could not say for sure, I'm no honemeister. All I can assume is that the angle is not fully forming to the edge, creating a multi angled edge. I really am not sure. I know people speak of finding the right degree of angle for the right edge of shaving. But you would think any decent edge should be able to atleast shave with. I would say spend more time setting the perfect edge on the rougher grits. Than smooth out the scratched surface of the edge on a fine. Than strop. My understanding is that most of an edge is in the lower grits. The fine just makes it smooth and buttery. Hope this was any help at all although I'm sure you figured most of this, lol.
