Ion select option in ionic 6.18 & vue 3 not saving selections

I am using ionic version 6.18 with vue3. The list of items to be generated shows and multiple items can be selected. However when I check the firebase collection, The options that were selected are not there. Here is my code from the template

    <ion-label>Services Provided</ion-label>

    <ion-select  multiple="true" cancel-text="Cancel" ok-text="Done">

      <ion-select-option v-model="formValues.service" v-for="service in serviceList" v-bind:key="service" >





this code is in the setup in the script:

const serviceList= [ ‘AC Services’,‘Seamstress’, ‘Clothing Design’,‘Carpentry’,‘Taylor’]
