Increased effect of Non-damaging ailments for Brittle doesn't work.

I have about 60% increased effect of non-damaging ailments and my base brittle that's on the ground stays as 5%. The brittle I attempt to inflict does not change substantially with casts through secrets of suffering with or without these points to increased effect. 0.1-0.5% difference when testing the bosses in Strand.

There have been multiple other bug reports about the non-damaging ailments being bugged but there has not been any response.
Edit: Removed Action speed off this bug report and only discovered bumping but do not know how to remove this post.
