For author information the original author-bio.php code is
<?php echo __( 'Author:', 'verbosa' ) . ' <strong' . cryout_schema_microdata( 'author-name', 0) . '>' . esc_attr( get_the_author() ) . '</strong>'; ?>
I noticed that the HTML output of the esc_attr( get_the_author() ) is < span class='p-author h-card'> Khürt Williams< /span>
When I remove the esc_attr() function call I get the expected output <span class='p-author h-card'>Khürt Williams</span>.
