Note also thatauthor={Zanthony1, Anthony2 and Anthony3},is a list of two names, not three. All authors must be separated withand, commas are only used to separate parts of the same name, see https://tex.stackexchange.com/q/557/35864 and https://tex.stackexchange.com/q/36396/35864. – moewe Aug 18 '19 at 04:04biblatexwould have been the appropriate tag, since your document loads the package and the question is specifically about output produced bybiblatex. Note thatcross-referencingis not the same as the genericciteorbibliographiestag.cross-referencingis about\labeland\ref. – moewe Aug 18 '19 at 04:06
