Issue with public label

Hi! thanks for the great plugin.

I think I found a bug. I can set the PUBLIC LABEL in the admin settings, but on the front end, I am still seeing: Code EAN:

I think these are the offending lines in class.product-gtin-wc-frontend.php:

121: 'label' => get_option( 'wpm-pgw-public-label', __( "Code EAN:", 'product-gtin-ean-upc-isbn-for-woocommerce' ) ),

204: $label = get_option( 'wpm-pgw-public-label', __( "Code EAN:", 'product-gtin-ean-upc-isbn-for-woocommerce' ) );

Other than this, the plugin suits my needs!
