Comment (by swartsr):

 This filter should fix it! The issue seems to be in the formatting.php
 file. Just a simple matter of leaving the "_" out of the accepted
 characters. Thanks!

 {{{
 function my_sanitize_html_class( $class, $fallback = '' ) {
         //Strip out any % encoded octets
         $sanitized = preg_replace('|%[a-fA-F0-9][a-fA-F0-9]|', '',
 $class);

         //Limit to A-Z,a-z,0-9,'-' '_'
         $sanitized = preg_replace('/[^A-Za-z0-9-_]/', '', $sanitized);

         if ( '' == $sanitized )
                 $sanitized = $fallback;

         return apply_filters( 'sanitize_html_class', $sanitized, $class,
 $fallback );
 }
 add_filter('sanitize_html_class','my_sanitize_html_class');
 }}}
