Deathwhisper Necro Epic 2.0Follow

I have tried to update my primary slot on my Character. My epic 2.0 is not listed. Is there anyway to fix this please?

LORE ITEM NO TRADE MAGIC ITEM
Weight: 2.9 Size: MEDIUM
Slot: NONE (Inventory)
Damage: 36 Delay: 30
Ratio: 0.833 Godly
Damage Bonus: 15 (lvl 70)
Comparative Efficiency: 145


I see why, Slot: NONE (inventory) it is Primary only
