scrolling issue

Another question. So I got my superior gollux ring (six slots clean) yesterday and spammed 5 advanced gollux scrolls. First fail next four pass. But when I looked at the upgrade count on the ring it said 2 slots left (no hammers used yet). Then I look on the screen chat bar and it says - upgrade count does not change due to "clean failure" effect. What the hell is that? I did not use a safety on it. Is this part of the new scroll trace system. Confused can someone explain pls.
Thanks
