Incoherent behavior with drill-down dimensions

[LaurentBerder]

Hi,

I used SenseSankey (thanks for your awesome work) with a drill-down dimension for the origin, and another drill-down dimension for the destination. When I drill down on the destination, I can still see the upper level of the origin dimension on the left. However, if I drill down on the origin, the destination dimension is also automatically drilled down. This destination dimension of my sankey diagram also gets drilled down to lower level if I filter on any other graph.

Basically, the only way I can see the higest level of my drill-down destination dimension on the sankey diagram is by using no filter at all.

Any idea why this would happen?

Here's my example with no filter (there's only one country for the destination, which is Brasil)

If I drill down on the destination, I get the detail of ports in Brasil, but still have the high level of world regions on the origin dimension on the left:

But if I go back to the start and filter on the origin (here I selected the region Northern Europe, getting European countries), the destination also gets drilled to the port level instead of showing only Brasil:
