[Решено] Translation Editor Not Working for Newly Created Products/Pages

Background of the issue:
I am trying to translate newly created products in English to German using WPML on my site скрытая ссылка. Previously translated items work fine with the translation editor.

Symptoms:
When I click on the + icon to translate new products into German, it asks me to add a new product from scratch instead of opening the translation editor.

Questions:
How can I solve the issue of the translation editor not working for newly created products or pages?
