vue eslint not throwing error on unused methods or computed properties

I am using Vue v2 and sublime 3 as text editor. For some reason eslint does not highlight unused computed properties or methods in my components. Other warnings / errors do work.

I followed general recommendations as per official docs

Here is my eslint file:

module.exports = {
  extends: [
    "eslint:recommended",
    "plugin:vue/essential",
    "plugin:vue/strongly-recommended",
    "plugin:vue/recommended", // Use this if you are using Vue.js 2.x.
    "prettier",
  ],
  rules: {},
};

My dev-dependencies:

  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-config-prettier": "^8.3.0",
    "eslint-plugin-vue": "^6.2.2",
    "sass": "~1.32.0",
    "sass-loader": "^10.0.0",
    "vue-cli-plugin-vuetify": "~2.4.5",
    "vue-template-compiler": "^2.6.11",
    "vuetify-loader": "^1.7.0"
  },

And lastly, my sublimeLinter settings:

// SublimeLinter Settings - User
{
  "linters": {
    "eslint": {
      "selector": "text.html.vue, source.js - meta.attribute-with-value",
      "env": {
        "PATH": "/Users/XXXXXX/.nvm/versions/node/v17.1.0/bin/"
      },
      "args": ["--env=es6"]
    }
  }
}
