Volcano + raging spirits stops work when Shapeshifted

When casting volcano to trigger raging spirits It functions As normal even its projectiles
But it stops when I Shapeshifted

it will not summon any additional raging spirits With it's projectiles hits a enemy

or trigger with other abilities on the volcano

This could be a type of weapon related issue. Not sure if raging spirits has weapon restriction but when u shapeshift u re weapon swapin
