I have the same problem!
you can try to modify from the line 147 of plugins/contact-form-7/includes/shortcodes.php

if ( WPCF7_USE_PIPE ) {
$pipes = new WPCF7_Pipes( $scanned_tag[‘raw_values’] );
$scanned_tag[‘values’] = $pipes->collect_befores();
$scanned_tag[‘pipes’] = $pipes;
$scanned_tag[‘labels’] = $pipes->collect_afters();
} else {
$scanned_tag[‘values’] = $scanned_tag[‘raw_values’];
}
//$scanned_tag[‘labels’] = $scanned_tag[‘values’];
