[Gelöst] I have disabled WPML from automatically creating menus

Background of the issue:
I use the automatic process but I have disabled WPML from automatically creating menus: I met issues with the translation of my AVADA main menu & their mega menus (They are well translated but are not displayed in front) andI tried to find a solution but I did a mistake, using the manual synchronization feature in WPML.
Now menus are no more displayed in secondary languages (deutch - dutch).

Symptoms:
Menus are not displayed in secondary languages (deutch - dutch).

Questions:
How to fix the issue of menus not being displayed in secondary languages and reactivate the automatic translation of menus?
