Villager badges completely broken

Villager badges don't show their levels properly:

Level 1 - Iron Badge
Level 2 - Gold Badge
Level 3 - Gold Badge
Level 4 - Gold Badge
Level 5 - Diamond Badge

This is how they work in Java Edition:

Level 1 - Stone Badge
Level 2 - Iron Badge
Level 3 - Gold Badge
Level 4 - Emerald Badge
Level 5 - Diamond Badge

 

This is NOT a parity issue. Villagers shouldn't have the same badge shown for 3 different levels.
