Echoing Rupture Crater Map valdo map not spawning reward chest

There was no chest after clearing whole valdo map and completing abyss by opening abyssal trove.

The map is Echoing Rupture Crater Map and reward should be Amanamu's Gaze.

Here is screenshot of opened trove and monsters remaining.


There were feared ground effect even after defeating them so that seems odd because I dont recall seeing it in other valdos


I am playing guardian with shrine node and using spectral tigers from new farrul ascendency.
There was Alva encounter which I completed too.
And yes I did go through the whole map multiple times.
