I am using Shoppica2 2.2.2 with Opencart 1.5.5.1.

When customer order, sometimes the product options are not showing at Sales>Orders> page.
Only I can see the product name, but no option, even though I set the option as required.

But sometimes, it is shown even with the same products.

May I know that is because I use the custom theme checkout?

Your help will be really appreciated. Thanks!
