The "X remaining" display for advancement criteria includes optional criteria, which can mislead players into thinking multiple criteria are required, when in fact the advancement will trigger if any one of the criteria are completed.

For example, the Nether advancement "War Pigs: Loot a Chest in a Bastion Remnant" states "4 remaining" criteria, when in fact this refers to four different types of chest, where opening any one of the four types will immediately trigger the advancement.
