vue.js - Vuex store update but DOM is not

I've looked through all the posts about this subject and can't seem to find an answer. My Vuex store IS updating fine, but the DOM is not.

This is a screenshot of what is going on

I have a getter called returnAmazonCredentials

returnAmazonCredentials(state) {
  return state.amazonCredentials
},

I import it like this:

computed: {
  ...mapGetters('amazonCredentials', [
    'returnAmazonCredentials',
]),

returnAmazonCredentials is an array and so I use it in my DOM with a v-for

v-for="(cred, index) in returnAmazonCredentials"

And I also use getters and setters to update the elements in the array. Here is one example

sellerId: {
  get() {
    return this.returnAmazonCredentials.merchant_id
  },
  set(value) {
    this.$set(this.returnAmazonCredentials[this.credIndex], 'merchant_id', value)
  }
},

this.credIndex is set when an element is clicked

When I want to remove an element from the returnAmazonCredentials array I do this:

this.returnAmazonCredentials.splice(index, 1)

The Vuex store is updated perfectly, while the DOM still shows old data that no longer exists in the store. I've tried:

this.$nextTick() as well as this.$forceUpdate()

No luck.. Where did I go astray?

EDIT: This is all my code in my component

You should dispatch an action that remove that item :

   sellerId: {
      get() {
        return this.returnAmazonCredentials.merchant_id
      },
      set(value) {
        this.$store.dispatch('removeCredential',this.credIndex)
      }
    },

store :

  mutations: {
    REMOVE_CREDENTIAL (state,index) {
      state.amazonCredentials.splice(index, 1)
    }
  },
  actions: {
    removeCredential(context,index) {
      context.commit('REMOVE_CREDENTIAL',index)
    }
