woocommerce-order-item-meta not showing up for order items

Hello,
I experimented with the free version of the plugin and got great results. I upgraded to the premium version because I wanted to also show recommended products in the email. However, when I upgraded, the woocommerce-order-item-meta is no longer showing up in my emails (looks like it may be one version number higher). Could you please help me get that information back?

Thank you very much in advance!
