I'm Confused about Ennard

So, in night 5 of Sister Location and the Custom Night, Ennard is using Baby's voice. In Pizzeria Simulator, Molten Freddy is using Funtime Freddy's voice.

Makes sence

But in UCN, Ennard's voice lines are just static screeching similar to Nightmare Mangle, while Molten Freddy is still using Funtime Freddy's voice.
