Aspect of Numbing Wrath and Fury over time gives too little Fortify

I have the Tuskhelm of Joritz the Might and The Aspect of Numbing Wrath.
It’s the only source I have for gaining Fury over time, and it seemed like it didn’t work at all.
It does, but this combination gives me 2 Fortify every tick, where as I should gain 22 with the level of aspect I’m using.

With Aspect of Berserk Fury, I should get 55 Fortify per tick, but it gives me about 5 per tick total.
It should probably be more considering I also have Prolific Fury.

This is either terrible scaling or not working as intended.

… And now it stopped working entirely. Re-equipped and re-logged to no avail.
