Methodical Dash Not Reducing Cooldown by 3secs

Methodical Dash - Dash has 1 additional charge and its Cooldown is reduced by 3 seconds.

When I equip this node on my skill tree, it only reduces the Cooldown by 1.9 seconds. The Cooldown says 11.4 seconds before selecting Methodical Dash, and 9.5 seconds after equipping Methodical Dash.

The additional Charge does, however, seem to be working correctly.

as for today, the same bug still present. Additional charge works, but cooldown is not reduced, the same 9 seconds as for basic skill for all three charges. Even the description of the node does not appear in the skill overview screen when you hover the cursor over it in the skill bar. The opposite node - disciplined dash - appears when chosen though.
