Passive node not activating properly "Adrenaline Rush"

Currently using galvic shards with merc now.
And I have allocated passive points to "Adrenaline Rush" node as well as both
movement speed node beside it.
For some odd reason, the movement speed increase after kill is only 9.5% (should be 10%) on character sheet after a kill.

And Attack speed increase from recent kill from adrenaline rush does not trigger at all. the attacks per second rate does not increase after a kill.
