Thanks for your reply.
I’m not sure what you mean by ‘Sync feature’ but if you refer to the windows sync, used to sync multiple computers, I don’t use this at all. I might have customized my menus in the past. I can’t remember exactly, but it’s definitely possible. So maybe, to prevent overwriting my custom settings, some steps have not been executed? That’s the only thing I could think of. In fact not a big issue, I already have repaired all affected entries, which was easy with the menu editor.
Thanks for your support!
