VueDraggable of Sortable is not working properly and send the choosed item to the first on init

Question

I'm using Vue.Draggable in my Nuxt project. i used it in some pages and component and every thing is fine. but on one of my pages it gives me a silly problem!! when page is loaded, it send the chosen item to the first!! after that every thing works fine! even if i choose and unchoose without moving, things works fine!! i tried to check if the choosed went to first of array move it again properly. it worked when the chosen item is the first if array but if i choose others than first, on 2nd try it move another item too!! so i'm kinda stuck.

here is the code: btw there are some variables and methods that u cant find them like cmsListItems. they are globally added to my project

template:

<draggable v-model="myItemsArray" @end="onEnd" @choose="onChoose" @unchoose="onUnChoose" v-bind="getOptions()">
    <transition-group type="transition" name="sortable_transition">
      <categorylistcard v-for="(category, index) in cmsListItems" 
      listtype="cat"
      :key="category.id" 
      :cat="category" 
      :index="index" 
      :showforsub="showForSub"
      :parentarr="parentArr"
      @addnewsub="addNewCat()"
      :sub="true"
      :sublvl="true"
      :sortable="true"
      :btntitle="lang.addsubcat"
      />
    </transition-group>
  </draggable>

script:

export default {
    data(){
      return{
        oldIndex: '',
        newIndex: '',
        dragOptions: {
            ghostClass: "sortable_ghost",
            chosenClass: "sortable_chosen",

            disabled: false
        },
        isMoved: false,
        myItemsArray: [],
        originalItemsArray: [],
        choosedItem: null
      }
    },
    methods:{
          // ***** Reorder By Sorting *****\\

          this.isMoved = true

I kinda hacked through it, so i don't recommend it!!

I got the chosen item with @choose and in my @end checked if first index of my array is the chosen item, unshift array and add the chosen to newIndex with splice() like bellow:

setTimeout(() => {
  if(this.myItemsArray[this.oldIndex].id === this.choosedItem.id || this.myItemsArray[0].id === this.choosedItem.id){
    let arrayOfItems = [...this.originalItemsArray]
    arrayOfItems.shift()
    arrayOfItems.splice(this.newIndex,0,this.choosedItem)
    this.setCmsListItems(arrayOfItems)
    this.myItemsArray = [...this.cmsListItems]
    this.choosedItem = null
  }
}, 1);
