Complex modification not working on Sonoma

macOs: Sonoma Karabiner: 14.13.0

Hi,

I am trying to use some complex modifications (one at a time) here: https://ke-complex-modifications.pqrs.org/#swedish_mx_keys_programming

I have tried everything but it doesnt work at all. Can someone please help?

So far I tried only one modification using "add your own rule":

{
      "description": "Swedish keyboard, Right command + 7,0 => curly-brackets {}",
      "manipulators": [
        {
          "type": "basic",
          "from": {
            "key_code": "7",
            "modifiers": {
              "mandatory": [
                "right_command"
              ]
            }
          },
          "to": [
            {
              "key_code": "8",
              "modifiers": [
                "left_option",
                "left_shift"
              ]
            }
          ]
        },
        {
          "type": "basic",
          "from": {
            "key_code": "0",
            "modifiers": {
              "mandatory": [
                "right_command"
              ]
            }
          },
          "to": [
            {
              "key_code": "9",
              "modifiers": [
                "left_option",
                "left_shift"
              ]
            }
          ]
        }
      ]
    }

Also, Add a predifined rule doesnt show on search:

And if clicked on "Import more rules from internet", it doesnt really import:

It says will import, but doesnt really import:
