(Custom Items) Broadsword of the Forest lists Regen 2 effect, but does not work

The Broadsword of the Forest (in the Hard boss crates) lists "Grants Regeneration II While Holding", but holding the sword does not grant any regen. Fair chance this is known but reporting to be sure some related notes First, putting the regen 2 sword into your offhand should be taken into account (either it shouldn't give buffs in the offhand, or putting it into the offhand should be disabled) Second, the Vampiric Blade effect also might not work. (don't have one)
