After Update WooCommerce Order Tracking shortcodes not working

Hello,

I am facing a very strange issue. I just update both plugins to the latest version

– WooCommerce Email Template Customizer
– WooCommerce Orders Tracking Premium

Everything was working perfectly fine, until a customer pointed out the tracking number and the shipping carrier name is no longer visible in the email.

I just checked and he is correct. I tried everything but it seems that all WooCommerce Orders Tracking shortcodes are not working. The just show blank even on the test emails.

Can you please help?

Thank you!
