I'm using the small collar from the Easy Mob Farm mod. In the config, only the minecraft:chicken, minecraft:cow, minecraft:donkey, minecraft:horse, minecraft:pig, and minecraft:sheep are working. It doesn't allow me to add any other mob names at all. I am also playing on a server, but I have no idea how to fix this config where all mobs can be captured by the collar.

Here is the modpack I'm using (aka the other mods being used)
