This is a temporay (unformatted) citation but where it wouldn’t print the author (hide author option). if you click update citations and bibliography it will format them, but without the author in a Author, year style.
You can get Endnote to still insert the author if you edit and turn off the option to the option to “Omit Author and/or Year from formatted citations if removed from temporary citation” in the “formatting” preferences in Endnote. (edit>preferences)
see attached image for the appearance of those settings dialogue.
