Falconry - "Side by Side" bugged?

Ive put 2 points into “Side by Side”. So every time I use for example a bow attack like explosive trap with blast rain and hit an enemy with it, I should see a 10% decrease of the cooldown of falcon strike.
But when its on cooldown, I dont see any change when I use explosive trap/blast rain.

Is my thinking wrong or is the skill bugged?

Report here Bug Reports - Last Epoch Forums if you suspect it is a bug

Did you take “impact trigger” ? I couldn’t spawn ballistas when I had it, I believe that when traps do not arm and explode, they do not “detonate”

No, i didnt take “impact trigger”. Im starting to think its a bug. I postet a thread in the bug reports, but maybe I read somethink wrong or dont unterstand something.
