W/press SEO – Twitter Card Meta HELP!

Each time we update W/Press SEO the twitter card creator meta does not update properly.

after update it reads <meta name=”twitter:creator” content=”@https://twitter.com/safetymatters”/>

it should read <meta name=”twitter:creator” content=”@safetymatters”/>

The following has to be pasted into the core file in order to correct it..

public function author_twitter() {
	if ( isset( $this->options['twitter_site'] ) )
		echo '<meta name="twitter:creator" content="@' . trim( $this->options['twitter_site'] ) . '"/>' . "\n";
	}

Any ideas on how to fix this please.
