vue el-tree数据回显问题？

Question

页面HTML

<el-tree
                ref="tree"
                style="min-height: 300px"
                show-checkbox
                :indent="0"
                :data="treeData"
                :props="treeProps"
                node-key="id"
                :check-strictly="checkStrictly"
                :default-expand-all="true"
                :default-checked-keys="checkedMenuIds"
                :render-content="renderContent"
                @node-expand="handleExpand"
                @check="handleBucketClick"
              >

获取数据回显方法：

getRoleMenus() {
      getMenuAuthList({
        roleId: this.form.roleId,
        appId: this.form.appId,
      }).then((res) => {
        // console.log(res.menuReq);
        this.checkStrictly = true;
        // 获取授权后id回显
        this.$nextTick(() => {
          let arr1 = [];
          let arr2 = [];
          res.menuReq.map((i) => {
            // console.log('---', i);
            if (i.btnIds) {
              arr1.push(i.menuId);
              i.btnIds.map((j) => {
                arr2.push(j);
              });
            } else {
              arr1.push(i.menuId);
            }
          });
          this.checkedMenuIds = [...arr1, ...arr2];
          console.log('树回显', this.checkedMenuIds);
          this.$refs.tree.setCheckedNodes(this.checkedMenuIds); //给树节点赋值
          console.log('this.$refs.tree', this.$refs.tree);
          this.checkStrictly = false;
        });
      });
    },

数据获取到了打印也有数据

但是页面上缺是这个样子，有的勾选了，有的没有勾选

一直找不到问题
