Line break problem on real email, not showing on editor

Hello, I use a custom template created with this plugin, the editor shows the shortcode {order_partial_refund} as an inline text, but on the real email sent from WooCommerce, the text is divided into 3 lines, see the screenshots for reference.

Note: the shortcode {order_number} is included in the sentence, and it shows properly in one line, maybe you could use the “trim” function to remove the extra lines.

Thanks and kind regards.
