Data for Model does not show (except record ID#) plus Warning for line 689

Hello,

Since the code snippets (below) are a little long, first want to say I appreciate the help!

Here's the problem I'm having:

I created a custom model and custom database table, but when I click on the model ("States Model") the editor shows all 63 IDs for the 63 records in the table, but none of the data fields are visible. When I open the database table through LocalWP (AdminNeo), all the data is present for all the records.

When I click to edit one of the records (or try to add a new record), I receive this Warning:

Warning: Attempt to read property "post_title" on null in /home/ls/Local Sites/bptest-backup-26-02-17/app/public/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-post-types.php on line 689

This is the code from the .php file. Line 689 is the echo statement:

/**
	 * Output extra data on post forms.
	 *
	 * @param WP_Post $post Current post object.
	 */
	public function edit_form_top( $post ) {
		echo '<input type="hidden" id="original_post_title" name="original_post_title" value="' . esc_attr( $post->post_title ) . '" />';
	}

In case some background information is helpful. The model I'm trying to create is for geolocation/mapping and will only be used for looking up values. Since it's census bureau / tiger web data, it will be checked for accuracy once or twice a year, but that's about it. In other words, I don't need a post for the data, but I would like to see it in the back end for testing purposes, etc.

Cutting and pasting, messed the spacing up, but here's the code I used to create the model / custom table / metabox:

// Step 1: Register a model.
add_action( 'init', function() {
	mb_register_model( 'statesmodel', [
