Blood Mage - Gore Spike

Hello
I took the node "Gore Spike (1% increased Critical Damage Bonus per 40 Life)" in the ascension tree
Why is the effect of this node not displayed in the skill window.

Before I took it, the critical multiplier was 172. After I took it, it remained the same.

At the moment, I have 985 life - it turns out the multiplier should give a 24 multiplier. But why does the value in the skill description not change? Is this some kind of bug or does the skill not work?
