antdVue 下拉多选定制回填内容

Question

<a-select
                    mode="multiple"
                    style="width: 68%"
                    v-model="info.users"
                    @change="handleChangeSelect"
                    option-label-prop="label"
                >
                    <a-select-option 
                        v-for="item in filteredOptions" 
                        :key="item.guId" 
                        :label="item.trueName" 
                        :value="item.guId">
                        {{ `[${item.userName}]${item.trueName}` }}
                    </a-select-option>
                </a-select>

配置了option-label-prop，为啥回填的内容还是value不是label啊
