<div class="wrap classify">

        <div class="classifyCheckbox">
          <label>vue.js</label>
          <input type="checkbox" value="vue.js" v-model="blog.classify">
          <label>javascript</label>
          <input type="checkbox" value="javascript" v-model="blog.classify">
          <label>CSS</label>
          <input type="checkbox" value="CSS" v-model="blog.classify">
          <label>jQuery</label>
          <input type="checkbox" value="jQuery" v-model="blog.classify">
        </div>
      </div>
 data() {
    return {
      blog: {
        id: null,
        blogTitle: "",
        blogContent: "",
        classify: [],
        type: ""
      },
      types: ["",""],
      submited: false // 
    }
  },
created() {
    // 
    this.blog = this.$store.state.presentBlog;
  }

vue is responsive. Your four v-model share a variable. The state of your four checkbox must be the same, and one changes

this place

created() {
  // 
  this.blog = this.$store.state.presentBlog
}

after getting the information, the classify of blog is not an array, is it?
