The game doesn’t seem to display the proper Echo level.
I am level 86 now.
In the Monolith it says Area Level: 86 (scaled)
Entering an Echo it says Echo level 90
Inside it says that area name, but Area Level: 86 (scaled).
Most of the time.
Entering a Tomb once, it started saying Level 90.

Then just now I entered a Cemetery, it said Area Level: 86 (scaled) all the while up until I fought the boss at the end of the instance where the thing switched in front of my eyes to say Area Level: 90.
update: This doesn’t seem to have anything to do with the Tombs or Cemetery (i.e. the league), it just switched in front of my eyes from 86 scaled to 90, just mid-echo. Perhaps it is triggered by some target/quest update or similar, idno.
