Some of the new sounds for goats have duplicate sound ids for the same sound pool. The duplicated ids are:

•  minecraft:entity.goat.eat is duplicated by minecraft:entity.goat.screaming.eat
•  minecraft:entity.goat.long_jump is duplicated by minecraft:entity.goat.screaming.long_jump
• minecraft:entity.goat.ram_impact is duplicated by minecraft:entity.goat.screaming.ram_impact

You can test them by running:

/playsound minecraft:entity.goat.eat ambient @p

then:

/playsound minecraft:entity.goat.screaming.eat ambient @p

the same can be done for the other sounds just change the namespace in the command.
