Problem with the display of collections in the table

There was a problem with the display of collections in the table, I do not yet understand how to solve it.

/imports/collections/posts.js

import SimpleSchema from 'simpl-schema';

console.log('import post file');

SimpleSchema.extendOptions(['autoform']);

Posts = new Meteor.Collection('posts');

Posts.attachSchema(new SimpleSchema({
    title: {
        type: String,
        max: 60
    },
    content: {
        type: String,
        autoform: {
            rows: 5
        }
    },
    createdAt: {
        type: Date,
        label: 'Date',
        autoValue: function() {
            if (this.isInsert) {
                return new Date();
            }
        }
    },
    owner: {
        type: String,
        regEx: SimpleSchema.RegEx.Id,
        autoValue: function() {
            if (this.isInsert) {
                return Meteor.userId();
            }
        },
        autoform: {
            options: function() {
                return _.map(Meteor.users.find().fetch(), function(user) {
                    return {
                        label: user.emails[0].address,
                        value: user._id
                    };
                });
            }
        }
    }
}));

Posts.helpers({
    postTitle: function() {
        if (this.post) {
            return Posts.findOne(this.post).title;
        }
    }
});

export default Posts;
