How to use custom_tpl

I have used this plugin to filter products by category and it is really a great plugin.

I tried to use a custom template using the custom_tpl attribute so I can modify a little bit the products displayed.

This is the current short code that I am using:
[woof_products per_page=6 columns=2 is_ajax=1 custom_tpl='woof_tpls/custom-product-cat.php']

This is the code inside: custom-product-cat.php

<?php
	$args = array(
		'post_type' => 'product'
		);
	$loop = new WP_Query( $args );
	if ( $loop->have_posts() ) {
		while ( $loop->have_posts() ) : $loop->the_post();

			//global $product;
			//echo $product->post->post_title;
			//
			wc_get_template_part( 'content', 'product' );

		endwhile;
	} else {
		echo __( 'No products found' );
	}
	wp_reset_postdata();
	
?>

The output of the code above is not correct because it displays the same products from a single category for every pagination.

Do you know that is the correct code to display the Product Title or Product Image correctly? Any idea is appreciated.
