Disintegrate node"Paralyze" is fully not working

The skill node “PARALYZE” of Mage’s skill Disintegrate is not work. It’s said Shock inflicted by Disintegrate lasts longer and Disintegrate deals more damage per stack of Shock on the target. The more damage based on Shock stacks on target is not work. this is a big bug, my Light Disintegrate only have 30% damage because of this node’s not wrok

I am currently having same issue
