Skill tree point allocation bug (Interaction with Intuitive Leap)

My character, WiseProfOak, is unable to allocate the intelligence passive just left of the one right above the "Lord of the Dead" notable. I have Intuitive Leap socketed in the jewel slot immediately above that next to the power charge node. I think the game is reading the int node as being allocated due to the Intuitive Leap jewel, and not letting me build nodes onto it that are outside of the jewel's radius, however this clearly can't be the case, as it is the only node connecting that jewel socket to the rest of the tree:



It has the red "Requirements not met" when I mouse-over.

And yes, I have a skill point available.
