This thread is resolved. Here is a description of the problem and solution.
Problem:
The client was experiencing an issue where orders created in the admin zone were defaulting to Slovak, despite the admin content being set to English. Additionally, there was a problem with sequential order numbers not being used correctly, with the first number being skipped.
Solution:
We recommended updating all outdated plugins and the WordPress core. After these updates, we asked the client to verify if the issue was resolved on a Sandbox site. We also ensured that the language information was correctly added to the orders. If you're experiencing this issue, we recommend checking for any outdated plugins or WordPress core updates and ensuring that your WPML and WooCommerce installations are up to date. For further guidance, you can refer to this documentation.
