Vixen's Curse overlaps doesn't change damage past two with Awakened Spell Cascade

What is the behaviour in-game?

When using Awakened Spell Cascade, PoB shows that 3 overlaps has no damage increase. However, testing in-game, I can tell my damage is significantly faster and higher than using normal Spell Cascade with just 2 overlaps.

What is the behaviour in Path of Building?

When trying to set overlaps to 3, the damage does not change at all. The damage remains the same at 2 overlaps.

How to reproduce the issue

Use my PoB link.
I did some testing and adding a custom field of 11% reduced Cooldown Recovery Rate seems to allow the third overlap, but my damage is the same as two overlaps.

I am not quite sure what is going on, but it seems the overlaps are hardcapped with a certain CDR? From various guides, and data on the internet on the build nobody has mentioned this being a thing. Not sure if it's a bug or if some other behavior is being applied behind the scenes.

Empieza cargando la build de PoB enlazada y reproduciendo Vixen's Curse con Spell Cascade normal y Awakened Spell Cascade con dos y tres solapamientos. Compara el daño resultante y el comportamiento del cooldown, incluido el caso personalizado indicado con un 11 % menos de Cooldown Recovery Rate. El trabajo estará terminado cuando Path of Building refleje correctamente el daño del tercer solapamiento dentro del juego.
