AJAX submission no longer redirects after AIO update

It appears that in Form.php in the following function

	private function enqueue() {
		wp_enqueue_style( 'mbfs-form', MBFS_URL . 'assets/form.css', '', MBFS_VER );
		wp_enqueue_script( 'mbfs', MBFS_URL . 'assets/frontend-submission.js', array( 'jquery' ), MBFS_VER, true );

		$this->localize_data = array_merge( $this->localize_data, [
			'ajaxUrl'        => admin_url( 'admin-ajax.php' ),
			'nonce'          => wp_create_nonce( 'ajax_nonce' ),
			'ajax'           => $this->config['ajax'],
			'redirect'       => $this->config['redirect'],
			'confirm_delete' => __( 'Are you sure to delete this post?', 'mb-frontend-submission' ),
		] );
	}

'ajax' is always getting set to false, regardless of what the shortcode value is for 'ajax'.

Not sure why the new version always sets the ajax value in the javascript created by localize_data to "false" on my site, but I ended up having to revert back to the previous version of Frontend Submisssion, because that version works for me. I currently don't have the time to fully investigate the issue.

Also, two identical lines of javascript are created in <script id='mbfs-js-extra'> (the localized data). Not sure what's going on there, either, but that obviously wouldn't cause any problems.
