Mobs aren't showing name tag or disguising

An example of one of my mobs is

PeskyRabbit:
Type: SKELETON
Display: '&2Pesky Rabbit Lvl. 1'
Health: 15
Damage: 1
Equipment:
- 268:0
Drops:
- RabbitDrops
Options:
MovementSpeed: 0.18
AlwaysShowName: true
Disguise:
Type: RABBIT

It just spawns a regular skeleton with a bow

ALSO: None of the premade mobs in the ExampleMobs.yml work either
