Life Regeneration Node Bug - Druid Passive Tree

There seems to be a bug affecting the Shapeshifted Life Regeneration nodes on the Druid side of the passive tree. When allocating points to those nodes, the life regeneration appears to only apply to weapon set 2. Switching from weapon set 1 to weapon set 2 drops my life regeneration from 246.3 to 192. I’ve tried intentionally linking those nodes to weapon set 1 but the extra life regeneration doesn’t apply while linking those nodes to weapon set 2 provides the increase. The nodes that grant additional damage in the same cluster appear to be providing their bonuses to both weapon sets properly.
