@animedy: Hello Edo,
Go to => Child Theme Folder => functions.php and add the following Code.

function filter_category(){
add_filter(
	'get_the_archive_title',
	function ( $title ) {
		if ( is_category() ) {
			$title = single_cat_title( '', false );
		} elseif ( is_tag() ) {
			$title = single_tag_title( '', false );
		} elseif ( is_author() ) {
			$title = '<span class="vcard">' . get_the_author() . '</span>';
		} elseif ( is_tax() ) { //for custom post types
			$title = sprintf( __( '%1$s' ), single_term_title( '', false ) );
		}
		return $title;
	}
);
}
add_action('init', 'filter_category');

Let me know if this solves your issue.
Kind Regards,
Skandha
