Intuitive Link + Bane + Curse bugged

Hello! I've been working on a build using bane linked with curses linked with intuitive link to allow someone to apply my curses at a range. When my linked ally hits the enemy, it triggers bane but none of the linked curses are applied.
This seems like a bug as the wording of Bane is "linked hex curses are also applied to those enemies". They are in the link with Bane although the game doesn't show that its linked via the glow it would normally. When self casting the bane without intuitive link, the curses are applied.
Unless the wording of bane differs from how it works this seems to point to a bug.

Edit:
Looking around it sounds like the reasoning is that the curses are trying to be triggered by 2 different sources which disables the curse gems. Not sure if that's correct though.
