Author multiple article line bug?

Hmm. That and multiple names in the text was deemed incorrect.
An example that Paperpile compiled:

‘Network publics’, as (Ito M, Antin J, Finn M, Law A, Manion A, Mitnick S, Schlossberg D, Yardi S, Horst HA 2009) use the term

Got dinged for that and Chicago Manual says it should be et al?

Also, could you call it incomplete when there isn’t a location ie: New York
Because some of my references which Paperpile considered ‘complete’ eg not in the incomplete filter, but did not have location, and was dinged for it.
