Oracle Life Curse dice replacement doesn't work

[Feuerhai]

The moderate Curse of Outpouring Life is supposed to replace the dice in the heal spell from d8 to d12 if all your targets are living creatures, but it doesn't do anything. The code that is supposed to do it is as follows (also in the examples of the wiki for rule elements: damage dice), with the "all-living-targets" preventing any replacement no matter what you target.

{
    "key": "DamageDice",
    "override": {
        "dieSize": "d12"
    },
    "predicate": [
        "item:slug:heal", {
            "or": ["oracular-curse:stage:moderate", "oracular-curse:stage:major", "oracular-curse:stage:extreme"]
        },
        "all-living-targets"
    ],
    "selector": "spell-damage"
}

Totally didn't notice the checkbox in the actions tab that appears when you have the medium curse, sorry for bothering
