What I expected to happen was...:
@e[type=creaking], @n[type=creaking], etc. should work like other mobs do

What actually happened was...:
I was pretty sure that there is at least one creaking that is loaded,

but it returns "No entity was found"

Steps to Reproduce:
1. /tp @n[type=creaking] or /data get entity @n[type=creaking]
2. It'll return "No entity was found", which means the bug is triggered
