Remove part of shipping line

Hi @acidburnsmk,

You can remove that text with a single CSS rule, taking advantage of the PDF template action hooks, specifically wpo_wcpdf_custom_styles.

Actually, I have written already the code snippet for you to achieve it, here:

/**
 * PDF Invoices & Packing Slip for WooCommerce:
 * Add custom styles to the PDF documents 
 */
add_action( 'wpo_wcpdf_custom_styles', function( $document_type, $document ) {
    ?>
	.shipped_via {
		display: none;
	}
    <?php
}, 10, 2 );

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters
