The drop elder / shaper /conqueror map sextant is not doing what it described.

The description of these sextants: Final Map Boss in each Map drops an additional Elder / Shaper / Conqueror Guardian Map (Tier 14+) also has negative mods which is:
1. Map Bosses deal 100% more Damage
2. Map Bosses have 200% more Life

However, when enter map, the mod at your right says:
1. Unique boss deals 100% more damage.
2. Unique boss has 200% more life.

They are totally different, right？ Map boss is the natural boss of a map, unique boss... there are so many unique boss in a map, including the elder, the conqueror, the beyond boss, the breach boss...

After all, the sextant is not doing the thing it describe, its undoubtedly a bug, plz fix it, ty.
