why does result hook call multiple times?

[jumpingfrog0]

I found a problem, if request more than one queries, the result hook call multiple times and the response data is messy.

my code:

const categoryQuery = gql`
    query {
      category {
        rows {
          id name icon zindex
        },
        count
      }
    }`;
const cityQuery = gql`
    query {
      city {
        rows {
          id name
        },
        count
      }
    }`;

apollo: {
	getCategories: {
		query() {
			return categoryQuery;
		} ,
		update(data) {
			return data.category.rows;
		},
		result(data) {
                        console.log('****should print categories****')
			console.log(data.category.rows);
		},
		error(error) {
			this.$notify({
				title: '错误',
				message: '获取演出类型列表失败',
				type: 'error'
			});
		}
	},
	getCities: {
		query() {
			return cityQuery;
		} ,
		update(data) {
			return data.city.rows;
		},
		result(data) {
                        console.log('---should print cities---')
			console.log(data.city.rows);
		},
		error(error) {
			this.$notify({
				title: '错误',
				message: '获取城市列表失败',
				type: 'error'
			});
		}
	}
}

But I get the result:

---should print cities---               // correct
["cityA", "cityB", "cityC"]

****should print categories****         // correct
["categoryA", "categoryB", "categoryC", "categoryD"]

---should print cities---               // messy
["categoryA", "categoryB", "categoryC"]

More queries, the data result is more messy.
