You do not need to have Shortcode in Menu plugin with the last version. Instead of using Show in Menu option you will need to use the shortcode.
You can go to Appearance -> Menus -> Custom Link then set URL = # and Link Text = [gtranslate] then Add to Menu.
If that does not work for you, please post your website address, so I can check.
Thank you for info, but I still see same issue 🙁

Can I send you on email website link?
No, you must post it here or add a link to your initial post.
