[Resolved] Constant alert message not required (with CPT)

Problem:
You are using the classic translation editor in WPML to translate a manually created custom post type (CPT). After duplicating and separating the CPT, a persistent pop-up alert appears every time you make changes or save, warning that changes will be lost using the WordPress editor, although they are not.
Solution:
This issue occurs because the translation editor is still active for the post or the entire CPT. To resolve this, you can disable the translation editor for the specific post or the entire CPT. For detailed instructions on how to switch to manual translation and disable the translation editor, please visit the following link:
