The silent cave didn't complet (unique map bug)

i was doing this map boss,
I kill the boss and the map didn't complet, I die 2 times before kill him, but finally i could defeat the boss.

in summary, the boss drops: greater essences but not the skill atlas points and the map didn't complet the area. i will post the link of the image.
