[Closed] Impossible to translate menu correctly

Hello,

I read the article here : https://wpml.org/documentation/getting-started-guide/translating-menus/#easy-customizable-wp-menus-sync
And tried to translate my menus both trough the sync option and the full custom options.
I have the weirdest behavior ncluding:
- impossible to view the translated menu after saving change (but it is still indicated that the menu exists in between the ().
- the original menu has a copy of himself in the dropdown menu of the original version (french) when creating the translated menu.
- Some entries created in one menu are also created in the other menu.
- All entries created when sync the menu are not created in the translated menu but in the originale menu

Note that this is a staging website on wordpress.com. WordPress and all plugins are up to date.

Unfortunately because the website needs to go live on monday, I had to reset then delete the extension so I cannot give you access nor send you the debug info. So I am juste trying my luck to know if those behaviors are known and you would have a config or fix I can try out. Otherwise I will need to wait the go live then we can work on the staging website.

Thank you for your help.
