I'd say it could be you are using more pressure on your Shapton's than on your Japanese natural?
Anyways, go back and reset the bevel properly, making sure once it is done, the markings are uniformly removed all across the bevel.
That should be the trick as far as I can tell from the pics.
If there are grind issues on the razor that prevents you from getting all the markings off, then at least make sure you remove enough o have the apex of the edge clean and honed on both sides.
