Customer Meta Shortcode Bug

booster 3.2.2
booster plus 1.1.0

I am trying to show each customers email in their invoice by using the customer meta shortcode in the booster invoice template. I am using the shortcode below. When I use this shortcode an email is displayed but no matter what invoice I look at they all show the same email. Instead of showing the customer’s email for the particular order, it shows one customers email for all other customers invoices. so customer A’s email appears on invoices for customer B, C, D, etc. Looks like a bug.
