object-curly-spacing when the property is on it's own line

Question

My indent settings is 4 spaces, but as you can see in my screenshot, this snippet is auto-fixing to 2 spaces, then eslint is throwing the error.

here is the code behind the error

import Vue from 'vue'
import Vuex from 'vuex'
import state from './state'
import mutations from './mutations'
import actions from './actions'

Vue.use(Vuex)

export default new Vuex.Store({
  state,
  mutations,
  actions
})

I'm assuming object-curly-spacing is the culprit but I really don't know eslint very well.

my eslint config

----edit------

turns out the same error happens with a much simpler example

var thing = {
 test: 'a'
}

adding this to my config removed the error, still not sure where the auto-fix is coming from

"indent": [
  "error",
  4,
  {
    "SwitchCase": 1,
    "ObjectExpression": "off"
  }
]
