Vuex and computed sometimes work, sometimes they don't update the page.

1. Two identical functions, same method, one valid, one invalid
2. Invalid code:

<Row :gutter="10" style="margin-top: 10px" v-for="(col, index) in categoryList" :key="index">
    <Col span="4" v-for="(item, index) in col" :key="index">
        <category-info :info="item"></category-info>
    </Col>
</Row>
mounted() {
    this.getCategoryList()
},
computed: {
    categoryList() {
        let list = _.chunk(this.$store.state.category.categoryList, 6)
        return list
    },
    categoryTotal() {
        return this.$store.state.category.categoryTotal
    }
},
methods: {
    getCategoryList() {
        this.$store.dispatch("getCategoryList")
    }
}

3.categoryInfo

props: {
    info: Object,
},

4.store

const category = {
    state: {
        categoryList: [],
        categoryTotal: 0,
    },
    mutations: {
        GETCATEGORYLIST (state, data) {
            state.categoryTotal = data.data.length
            let categoryList = data.data
            state.categoryList = categoryList
        },
        DELETECATEGORY (state, typeId) {
            state.categoryTotal--
            state.categoryList = _.remove(state.categoryList, v => {
                return v.typeId != typeId
            })
        }
    },
    actions: {
      // category
        getCategoryList (context) {
            Util.ajax
            .get("/type/all")
            .then(res => {
                context.commit("GETCATEGORYLIST",res.data)
            })
        },
        deleteCategory (context, typeId) {
            Util.ajax
            .delete(`/type/delete?typeIds=${typeId}`)
            .then(res => {
                if(res.data.status == 0) {
                    context.commit("DELETECATEGORY", typeId)
                  }
            })
        },
    }
}

export default category

refresh the page-> mounted- > retrieve the data. At this time, the store has data changes, but the page is blank

.

another product list is valid in the same way, strangely, is it because the object of computed is an array? Or is there something wrong with the writing
