Galvanic Hammer not yielding any elemental damage

The passive "Galvanic Hammer" has following description: 12% increased physical damage with maces and 20% incrased elemental damage with maces.

It is easy to check that when you use a 2-hand mace (haven't tested 1-hand) the elemental damage does not get applied at all. By this I mean that the skill information which appears when you move your mouse cursor to your skill at your skillbar shows no extra damage for neither Glacial Hammer nor Lightning Strike.

This is verifiable by noting that given no elemental damage bonuses except Galvanic Hammer, the elemental part of Glacial Hammer and Lightning Strike is exactly the same as corresponding physical part. If the elemental part of "Galvanic Hammer" had worked for 2-h maces, the elemental part would have been larger.


EDIT: I have tested with 1-hand maces now. It is clear that that "Elemental" part of the bonus works with ONLY 1-hand, while the "Physical" part of the bonus work with both 1-hand and 2-hand maces. This is definitely a bug! It should be changed so that the "Elemental" part work on 2-hand maces too.

Post Edited, Found the bug.

Galvanic hammer also doesn't work for the offhand when dual wielding (tested with a dagger main/scepter off).
