Hi,
I'm using 7.1 version of betheme. But style.css loading twice 
...wp-content/themes/betheme-child/style.css?ver=7.1
...
wp-content/themes/betheme-child/style.css?ver=4.1.1
in function.php
	// Enqueue the parent stylesheet
	wp_enqueue_style( 'style', get_template_directory_uri() .'/style.css' );
	
	// Enqueue the parent rtl stylesheet
	if ( is_rtl() ) {
		wp_enqueue_style( 'mfn-rtl', get_template_directory_uri() . '/rtl.css' );
	}
	
	// Enqueue the child stylesheet
	wp_enqueue_style( 'mfn-child-style', get_stylesheet_directory_uri() .'/style.css' );
Could you help me? Thank you.
