Problem:
If you're experiencing alerts when editing a translated CPT post using WPML, it might be due to the settings of your WordPress Editor.
Solution:
We recommend reapplying the WordPress Editor option globally to stop receiving these alerts. To do this, create a test page and select "WPML Editor" for translations. Then, choose the option to use the WPML Editor on the entire website from the pop-up. This should resolve the issue.

If this solution does not apply to your case, or if it seems outdated, please check the related known issues and verify that you have installed the latest versions of themes and plugins. If the problem persists, we highly recommend opening a new support ticket for further assistance. You can do so at WPML support forum.
