If you have a search term, say Office, and you hit Duplicate, then the new item "Office - Copy" does not appear in the list of results. It should automatically appear here.
In my testing, it does populate the search results when creating a new item.
Make sure the search field is set to search in all items or in the same category as the original item. For an example, if you were searching in Favorites, duplicating the item wouldn't be in Favorites but in its own category.
Hope that helps, please let me know.
I saw it worked today. Perhaps I was not in All Items before. Thanks.
That's great, glad to hear it is working as expected.
