Zero not recognized

I’m trying to set a device to 0 using this german sentence: “Stelle das Rollo auf null”.

stelle rollo{Device} auf (0..9){Value}

Doesn’t matter if I’m using no converter, int or float, the zero (“null”) doesn’t get recognized.

        {
            "end": 20,
            "entity": "Value",
            "raw_end": 25,
            "raw_start": 21,
            "raw_value": "null",
            "start": 21,
            "value": "",
            "value_details": {
                "kind": "Unknown",
                "value": ""
            }
        }

Is anyone able to confirm this?

I confirm;
schließe den rolladen auf null prozent
no value for “null”

"entities": [
    {
        "entity": "position",
        "value": "",
        "value_details": {
            "kind": "Unknown",
            "value": ""
        },
        "raw_value": "null",
        "start": 26,
        "end": 25,
        "raw_start": 26,
        "raw_end": 30
    },

Thanks for confirming!
