Multiple VueSelect

I am obtaining from an API the data to fill a v-select type component, the component is filled correctly and I also obtain the options that the user already had assigned (multiple)

And the v-select component are filled correctly

But when i try to add another option occurs the next

Here is the Source Code

<validation-provider
        #default="validationContext"
        name="skill"
      >
        <b-form-group
          label="Skills"
          label-for="skill_id"
          :state="getValidationState(validationContext)"
        >
          <v-select
            v-model="itemData.skills"
            :dir="$store.state.appConfig.isRTL ? 'rtl' : 'ltr'"
            multiple
            :options="skillOptions"
            :clearable="false"
            :reduce="(val) => val.value"
            input-id="skill_id"
          />
          <b-form-invalid-feedback
            :state="getValidationState(validationContext)"
          >
            {{ validationContext.errors[0] }}
          </b-form-invalid-feedback>
        </b-form-group>
      </validation-provider>

Here i have the array of objects, with multiple elements

itemEdit.value.skills

Then map to get a reduced array with only the value and label

I have probed using only the label without value and the result is the same

const openEdit = item => {
  isSidebarActive.value = true
  itemEdit.value = item
  itemEdit.value.skills = item.skills.map(skill => ({
    value: skill.id,
    label: skill.skill,
  }))
  isAdd.value = false
}

Everything apparently goes right, the v-model match correctly with the available options, the problem comes when the user interact with the vSelect to add another item, the already selected items disappear

Thanks in advance

thanks for listen, the problem was solved removing:

:reduce="(val) => val.value"

From

<v-select
            v-model="itemData.skills"
            :dir="$store.state.appConfig.isRTL ? 'rtl' : 'ltr'"
            multiple
            :options="skillOptions"
            :clearable="false"
            :reduce="(val) => val.value"
            input-id="skill_id"
          />
