Sankey Node Hover Issue

Yes, the links have identical labels when appropriate. I am using the label as a mechanism to connect links to one another which allows for ‘mapping the route’ an individual takes.

This function is working appropriately. When hovering over any link, it highlights the ‘route’ a person took from node [0] to whatever their final node may be (node [-1], if you will).

However, my issue is that when hovering over any given node there is a random set of links (connected using identical labels) that gets highlighted from beginning to end. As I understand it, highlighting a node should only highlight the links from the previous/next nodes; not a set of links from beginning to end.

I’ve looked through the data (source, targets, values, labels) multiple times and everything is structured correctly, so I’m wondering if it’s a bug.
