Concoction not working with Concentrated Effect [3.185.503.673]

Currently using Shattering Concoction.

When i link it with Concentrated Effect the area becomes smaller, as expected.
But the damage is unaffected, would expect the damage to go up?

Note: Concentrated Effect is the first of the recommended support gems.
Note2: Elemental Armaments is recommended, but doesn't work with concoctions because it requires a weapon, but concoctions are unarmed.

Edit: Also doesn't work with attack area damage passives.

very surprised this isn't fixed yet, hoping for a fix soon

Still bugged as of right now - it reduces the aoe but doesn't give any damage on tooltip.

Same problem I guess with all concoction. Using Bleeding and having the same issues.

The AoE reduction is working though :(
