Very confusing – Dragon & Dinosaur Addons Free for Minecraft PE Review

This is kinda pointless cause it doesn't work I mean when ever I add it as a behavior pack it just makes giant bats that are "dragons" or giant creepers that are "Rex's" please fix this the default minecraft behavior pack just overrides it I know it's legit and all but it doesn't work pls fix this
