WooCommerce Email Customizer Translation Issue with TranslatePress

Dear VillaTheme Support Team,
I am experiencing an issue with your WooCommerce Email Customizer plugin where custom order meta fields are not being translated in emails, despite having translations configured in TranslatePress.
Environment Details:

Your Plugin: WooCommerce Email Customizer (latest version)
Translation Plugin: TranslatePress – Multilingual
WordPress Version: [Current version]
WooCommerce Version: [Current version]
Languages: English (default), Lithuanian, Italian

Issue Description:
I have custom appointment booking meta fields that appear in WooCommerce order emails:

Appointment Information: #305
Service: pop-up
Date: 22/08/2025, 10:50 – 11:10
Artist: Mažena Temp
Google Calendar: Link

These fields are coming from woocommerce_email_order_meta and include the following strings:

“Appointment Details”
“Appointment Information:”
“Service:”
“Date:”
“Artist:”
“Google Calendar:”
“Link”

Problem:

TranslatePress shows these strings as successfully translated in its interface
The translations appear correctly in the TranslatePress translation editor
However, when emails are sent in Lithuanian or Italian, these meta fields always appear in English
The rest of the WooCommerce email content translates correctly – only these custom meta fields remain in English

What I’ve Tried:

Verified TranslatePress has “Translate emails sent to user” option enabled
Confirmed translations exist in TranslatePress database
Tested with different language settings for orders
Cleared all caches

Additional Information:

The translations work correctly on the frontend of the website
Only email translations for these specific meta fields are affected
Standard WooCommerce email strings translate correctly

Could you please provide guidance on:

The correct way to ensure custom order meta fields are translatable in your Email Customizer
Any specific settings or configurations we might have missed
Whether this is a known compatibility issue with TranslatePress
Any hooks or filters your plugin provides for multilingual functionality

I would greatly appreciate your assistance in resolving this issue. If you need any additional information, debug logs, or access to test the issue, please let me know.
Thank you for your time and support.
