Boss/Dungeon crates - items say "Dungeon boss"

If you hover over the items in the boss/dungeon crates, they say "Easy Dungeon Boss" "Normal Dungeon Boss" "Hard Dungeon Boss" and "Nightmare Dungeon Boss". For the boss crates, this is inaccurate as they aren't "dungeon" bosses. For the dungeon bosses, this also isn't really accurate. I think the normal dungeon crate is a participation reward for playing the dungeon, while the legendary dungeon crate is for winning a dungeon.
