Bug with STR requirements

Hi,

Why are one handed maces triple strenght requirements as the two handed maces using Giants blood ?

Why a one hand mace used in one hand be 3x requirements? I think this is bugged.

If I use a two-handed in one hand it should be logically triple requirements.

When I take this node and use a two handed mace as a two hands, the requirements should be normal like when I do not take the node.

Could this node be activated only when I equip a shield or another weapon in my second hand while using a two hand mace? This would make more sense.

Thanks
