Aftershocks with Upheaval and Unabating not scaling properly

I’m using the Upheaval and Unabating nodes in the Earthquake skill to convert Aftershock into a damage over time ability (proccing from the idols that cause them on melee hit). However, these nodes do not seem to be working properly. I can visually see the aftershocks on screen but Unabating (15% more dot damage per point, gated behind the conversion) is not increasing the damage of the ability at all, (even on the tooltip) which is surely bugged somehow. Even more seriously, the Upheaval node itself is not giving the effect a damage over time tag which means it’s not scaling off of damage over time increases anywhere else on the character. This is surely unintended and bugged as it’s clearly implied by the description of the skill node (“Aftershocks are now damage over time”) and the existence of the Unabating node. If not, the tooltips need to be completely changed because it’s completely bizarre as a non-interaction. Please help!

Thanks!

There are screenshots here of the Aftershock tooltip with different numbers of points allocated in Unabating. It does not show any difference in the DPS which reflects the experience of trying to play with it!
