[Resuelto] My backend order management has an issue where the Product Add-ons selected by buyers do not appear ...

Background of the issue:
I am trying to ensure that Product Add-ons selections made by buyers are correctly displayed in the backend order details. The issue can be seen on this page: enlace oculto.

Symptoms:
Some orders do not display the Product Add-ons selections in the backend, especially when placed using the translated (English) page. The total order amount is higher than expected, indicating that the Product Add-ons field is not shown.

Questions:
Why are Product Add-ons selections not appearing in the backend order details?
Is there a specific issue with orders placed using the translated (English) page?
