Unique Map : Untainted PAradise : no completion not in Atlas (Zana)

I just got "Untainted Paradise" Unique map form Zana, i finish it, but the final bosse give me no Atlas COmpletion rewards, its not even listed in my Atlas and also its not available in the Map Stash Tab in the Unique section.

Its an old Unique map ? Zana can give maps not available on the Atlas ?

(Its the one with Beach biome, 0 drop and 363% xp from mobs).

OK Resolved, its a special unique, not in Atlas and not counting for completion, firt time i see it since beta lol :
