template not showing in custom widget

I made a custom widget and everything is showing fine in the back end. The widget is populated and the info saves. My problem is that nothing is showing on the front end. Not even simple html. I have shortened my code for easier reading. Just took out some of the settings. In the tpl folder, I have a file named address.php that should display the front end but I get nothing. Are there any common errors that would prevent it from showing on the front end? Not even the html shows. The widget displays on the back end and works just fine.

File structure

address-widget
folder assets
folder styles
folder tpl
address.php
address-widget.php

/*
Widget Name: Mosty Address Widget
Description: Displays a formatted address widget!'.


*/

class Address_Widget extends SiteOrigin_Widget {
	function __construct() {

		parent::__construct(
			'address',
			__( 'Mosty Address Widget', 'mosty' ),
			array(
				'description' => __( 'A formatted address widget', 'mosty' ),
			),
			array(
			),
			false,
			plugin_dir_path(__FILE__)
		);
	}
	
	function get_widget_form() {
		return array(
	
			'title' => array(
				'type' => 'text',
				'label' => __('Title.', 'mosty'),
				'default' => 'Contact Us'
			),
		);
	}

	function get_template_name($instance) {
		return 'address';
	}

	function get_style_name($instance) {
		return 'address-style';
	}
}
siteorigin_widget_register('mosty_address_widget', __FILE__, 'Address_Widget');
