Modify users list in WordPress

I’m currently trying to modify a column in the WordPress users list. But when I try out my code, I only get the last two ultimate member specific columns (Account status and assignment):

add_action( 'manage_users_custom_column', 'modify_users_column_content', 10, 3 );
function modify_users_column_content( $value, $column_name, $user_id ) {

    if ( $column_name === 'name' ) {
		$value .= '<span> |</span>';
	}

	return $value;
}

I’m not sure but I think that there is an issue with UltimateMember or a “special thing”. So can you may check this and help me out? Would be awesome! Thank you ??
