Woo commerce Booster Email Issue

Hi there,

I’m using the Booster for Woocommerce to send my emails upon customer orders and every few emails, the shortcode isn’t working, both on my end and the customer’s end. We’ll receive the actual email but the email shows up as all of the shortcodes themselves and not the info that they’re supposed to be displaying. Any ideas on where to begin to fix this? Thank you in advance!
