Zoglins sounds like PIGS

Why does Zoglins sound like PIGS? I even tried to playsound "mob.zoglin.say", "mob.zoglin.hurt", and "mob.zoglin.death" but all of them are PIG sounds.

 

HOW TO REPRODUCE IT:

1: Summon a Zoglin

2: Hit or Kill or wait for it to play sound effects

Or alternatively use playsound

EXPECTED RESULTS: Zoglin sounds

ACTUAL RESULTS: Pig sounds
