Problems with overwrite!

I have a problem about my child theme (file highstake-child). I need to translate the blog from english to portuguese but the child theme do not overwrite the modifications that I wrote.

File inc/extras.php
Original:

function highstake_lite_extend_archive_title( $title ) {
	if ( is_category() ) {
		$title = sprintf( esc_html__( 'posts in %s category', 'highstake-lite' ), '<span>' . single_cat_title( '', false ) . '</span>' );
	} elseif ( is_tag() ) {
		$title = sprintf( esc_html__( 'posts in %s tag', 'highstake-lite' ), '<span>' . single_tag_title( '', false ) . '</span>' );
	} elseif ( is_author() ) {
		$title = sprintf( esc_html__( 'posts by %s', 'highstake-lite' ), '<span>' . get_the_author() . '</span>' );
	} elseif ( is_search() ) {
		$title = sprintf( esc_html__( 'Search Results for: %s', 'highstake-lite' ), '<span>' . get_search_query() . '</span>' );
	} else {
		$title = esc_html__( 'Latest News', 'highstake-lite' );
	}
	return $title;
}

Translated:

function highstake_lite_extend_archive_title( $title ) {
	if ( is_category() ) {
		$title = sprintf( esc_html__( 'Publicações pela categoria %s', 'highstake-lite' ), '<span>' . single_cat_title( '', false ) . '</span>' );
	} elseif ( is_tag() ) {
		$title = sprintf( esc_html__( 'Publicações pela tag %s', 'highstake-lite' ), '<span>' . single_tag_title( '', false ) . '</span>' );
	} elseif ( is_author() ) {
		$title = sprintf( esc_html__( 'Publicações por %s', 'highstake-lite' ), '<span>' . get_the_author() . '</span>' );
	} elseif ( is_search() ) {
		$title = sprintf( esc_html__( 'Resultado da Pesquisa: %s', 'highstake-lite' ), '<span>' . get_search_query() . '</span>' );
	} else {
		$title = esc_html__( 'Últimas notícias', 'highstake-lite' );
	}
	return $title;
}
