Vuexfire duplicated objects returned when using collection.

I am trying to bind a collection with a where query. However, each time I bind the collection it returns an array with duplicated results as following:

[{Object 1 relating to doc 1},
{Object 2 relating to doc 2},
{Object 2 relating to doc 2},
{Object 1 relating to doc 1}]

The code I am using is the following:

// In my vuex store
const actions = {
  setEnquiriesRef: firebaseAction((context, ref) => {
    context.bindFirebaseRef('enquiries', ref).then((val) => {
      console.log('enquiries bound', val) // This val gives the output above, and is the same as the bound value
    })
  })
}

// In my vue component where I call the function:
let ref = firestore.collection('enquiries').where('uid', '==', 'Relevant uid')
this.$store.dispatch('setEnquiriesRef', ref)

Some notes:

• If the ref is a document it works as expected.
• If the ref is a collection without the where query the same duplication happens.
• This is using "vuexfire": "^3.0.0-alpha.14"
• If i simply run a one-time get on that reference it returns the correct data as expected (Not duplicated).
• It always loads the documents in a particular order (Either default or with orderBy), and the duplicates are always the reverse of this.

Update: I wasn’t understanding how the firebaseMutations were being registered, so I was adding them to each of my modules in my store. Which is obviously unnecessary and was causing the duplicate.

In case someone else lands here I had called ‘…vuexfireMutations’ from multiple places. Resolving that fixed the duplicates for me.
