Hey @dosta360,
Regretfully, there’s no option to change the word Label. You need to translate texts programmatically. I’ll show you a snippet but please bear in mind that custom coding is outside the scope of our support. The purpose of this is to only guide you or show you the possibilities in WordPress.
Before giving you the snippet, install a child theme first. If you don’t know how to do this or install custom PHP code, please hire a developer for assistance. Below is the code to be added in the child theme’s functions.php. I believe you see the word Label in the code and its made up translation Lebel. Change Lebel to something else. You can use that code to change other words in WordPress. Just remember that we do not support this so if you encounter an issue with this or need further enhancement, please hire a WordPress developer.
add_filter( 'gettext', 'wps_translate_words_array' );
add_filter( 'ngettext', 'wps_translate_words_array' );
function wps_translate_words_array( $translated ) {
$words = array(
// 'word to translate' = > 'translation'
// 'Posts' => 'Articles',
// 'Post' => 'Article',
'Label' => 'Lebel'
);
$translated = str_ireplace( array_keys($words), $words, $translated );
return $translated;
}

Hope that helps.
