Aftershock % from skill tree doesn't add aftershock chance

The aftershock skills from the tree doesn't add any aftershock for my slams. I'm talking about Split the Earth, which should add 10%, and Mace aftershock chance, which should add another 8%.

My ascendancy aftershock chance works fine so I'm at 20% aftershock chance for Rolling Slam and Sunder.

i'm having the same issue, so still not fixed

Same issue here. The Aftershock nodes for the maces are broken.
