Config morphs doesn't work

[ghost]

No matter what I type, the config I typed won't apply. For example I tried to reduce the zombie's speed by putting "speed": 0.05, didn't work. Tried to give a modded mob the ability to fly by "abilities": ["fly"], didn't work.

Provide full content of your morphs.json file.

"Zombie": {
    "abilities": ["sun_allergy", "hungerless"],
    "health": 20,
 "speed": 0.04,
    "hostile": true,
    "hands": true
},
},
"lycanitesmobs:manticore": {
    "abilities": ["fly"],
    "hostile": true
}

I don't know why speed at zombie is a little bit to the left, it isn't on notepad

Your JSON formatting is broken... you need to fix your JSON. In the documentation it says that.

At the moment, I’m on mobile, so I can’t fix it. Try yourself.
